ABSTRACT
Heat shock proteins Hsp70 proteins belong to the heat shock protein family, boost cells
survival in hostile environments, involved in many cellular biological processes. The
polymorphism of hsp70 gene relates to the possibility of tolerating different stress
conditions. This study was carried out during 1st April to 31th June 2016, 20 Arabi Rams,
known fertility, 2 – 2.5 years old, from the Agricultural Research Station / College of
Agriculture / University of Basra, Iraq, were used, Semen was collected by using the
artificial vagina, after training well. DNA extracted then Polymerase chain reaction(PCR)
amplified sequencing, BLAST analysis and multiple sequence alignment were carried out.
The results showed two haplotypes, haplotype G1 , haplotype G٢ compared with same
gene in GenBank, all mutations were silent except the mutation is site 514 was missense
appeared in G1. It concluded that the Arabi rams in Iraq have new polymorphism of
hsp70 gene which can help cope with difficult environmental conditions.
INTRODUCTION
Heat shock protein (HSPs) are a highly preserved polypeptides, lodging almost in
any cell, they were classified according to their molecular weights, one of their most
important roles is as like molecular chaperones and are decisively Participate in
maintaining protein homeostasis and cell survival (1). Hsp70 is a member of HSPs
family, which are spread in all living organisms, whether eukaryotic or prokaryotic (2,3),
which in addition to working as molecular chaperones, have immune functions( 4,5), but
its main role is folding the proteins and prevent the improper assembly of proteins (6).
Hsp70 has a significant role in protecting cells against cellular stress including heat stress

(7), by promoting cells tolerance to environmental changes and pathologic conditions (8).
The work of the Hsp70 can be summarized in three main axes in all organisms, prevent of
ingathering of proteins, corrected folded proteins that are exposed to misfolded and
dissolve and refolding of aggregated proteins under the stress conditions (9). These
functions of HSP70 as a molecular chaperone and cell protect versus heat stress, making it
able to denaturing proteins (10). On the other hand many studies have indicated a
relationship between the polymorphism of hsp70 gene and heat tolerance in Holstein cow
(11), chicken (12), in buffalo (13) and in sheep (14).The polymorphism of hsp70 gene
also affects reproductive performance of Farm Animal males, by reducing the various
stress conditions on the animals (15,16). Therefore, the hsp70 gene is an ideal biological
marker to resist heat stress in farm animals (17). No previous study in Iraq has been
conducted on the polymorphism of hsp70 gene in the semen of Arabi Rams in Iraq,
except for one study on the polymorphism of the hsp70 gene in Iraqi Holstein Bulls by
(18), therefore no information about the polymorphism of hsp70 gene in Arabi Rams.
This study aimed to identify the polymorphism of hsp70 gene in Arabi Rams.
MATERIALS AND METHODS
Animals and semen collection
Twenty Arabi Rams, known fertility, 2 – 2.5 years old, from the Agricultural
Research Station / College of Agriculture / University of Basra, Iraq, were used in the
present study. During 1st April to 31th June 2016. Semen collected from Rams by using
the artificial vagina method, specialized artificial vagina for sheep (after training well).
DNA extraction
DNA was extracted from semen samples using Chelex ( Sigma Aldrich, USA) as
described by (19). Concentration and purity of DNA was estimated by using Nanodrop
system (Nano Drop thermo scientific 200, USA). 1.8 was adopted as the best purity of
260/280 ratio (20)
PCR amplification and Sequencing
Amplifications were performed according to First BASE Laboratories / Malaysia,
in 25 μl reactions (Table 1), to amplify conserved region within the hsp70 promotor
,primer was used as in table 2 , the PCR amplification cycling protocols of PCR
amplification as in table 3. PCR product was detected on 1.5 % ethidium bromide stained
agarose gel, wih size 1926pb approximately (Fig 1), as described (18).
PCR products Purified and sequenced in First BASE Laboratories / Malaysia .
(www.base-asia.com) . Nucleotides sequence alignments, were done using Geneious
version 10.1.3 software. BLAST Analysis was carried out on website
(www.ncbi.nlm.nih.gov. ) Multiple Sequence Alignment and compared with same gene in

RESULTS AND DISCUSSION
The results of nucleotides sequence analysis and the Multiple Sequence Alignment
( MSA) compared with heat shock protein hsp70 gene of sheep in the gene bank, suggest
a presence two new haplotypes (Figure2) , classified as two groups :
First group : haplotype A : showed no match at 100% with other nucleotides sequence
of other group or in Gene Bank heat shock protein hsp70 gene, the nucleotide in position
1308, T was substituted by the nucleotide C (T <C), a silent mutation that did not
encoding a new amino acid, 10 rams were found in this group.
Second group: haplotype B : in comparison with the first group and the same gene in
Gene Bank, the nucleotide C was substituted with the nucleotide G (C <G), a missense
mutation that resulted in a change in the amino acid encoding (Histidine change to
Aspartic) in the position 514, a mutation not previously recorded in sheep except in
Chinese sheep by (21) , registered as a patent with ID CN104745552A but did not match
the results of the current study. In addition, nucleotide G was substituted by nucleotide A
(G <A) in the position 1524, a silent mutation, 10 rams were found in this group.
The (MSA) of hsp70 gene showed that the ratio of A and B haplotypes were 99.89% and
99.84% respectively with the same gene in the Gene Bank, accession number
NM_001267874.1 (22 ), these results are consistent with Pawar et al., (23) and Banerjee
et al., (24) in the possibility of polymorphisms of hsp70 gene in sheep, but the results are
not consistent with any previous study in the position of mutations, and may be due to the
fact that the current study is the first of its kind and was not preceded by any other study.
These mutations in hsp70 gene may refers to the development of this protein through the
positive election among domestic animals (25).
On the other hand the silent mutations may effect on the role of translated protein through
diverse cellular mechanisms (26), and it lead to polymorphism to the hsp70 gene, that’s
associated with the semen quality (27).

As for the missense mutation that occurred in haplotype B due to the change of Histidine
amino acid to the Aspartic, it may improve the quality of semen (28, 29 , 30).

CONCLUSION
This study was showed two haplotypes of hsp70 gene in the Arabi rams in Iraq, due
to the occurrence of mutations in more than one location, suggesting that genotypes of
hsp70 could have been genetically modified to adapt to environmental conditions.
