Heat shock-related 70kDa protein 2 (HSPA2) is encoded by the HSPA2 gene localized in the human chromosome 14q23.3. It is one of the isoforms of HSP-70 and is a cytosolic family member that undergoes methylation. HspA2 shows 85% homology to HspA1L isoform.
Synonyms: Anti-Heat shock 70 kDa protein 2 antibody produced in rabbit; Anti-Heat shock-related 70 kDa protein 2 antibody produced in rabbit
Storage: -20C
Application: Anti-HSPA2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: Heat shock-related 70kDa protein 2 is a testis-specific member of the HSP70 family and is correlated with sperm maturity, function and fertility. The protein is important for cancer cell growth and metastasis. It is identified as a potential cancer-promoting protein expressed at abnormal levels in a subset of cancers. HSPA2 has an important role in esophageal squamous cell carcinoma (ESCC) and overexpression of this gene may contribute to the malignant progression of ESCC. Its expression significantly correlates with sperm concentration and morphology. HSPA2 may play an important role in capacitation and fertilisation processes.
