    HSP70/HSPA1A Summary & Protein Information

    HSP70/HSPA1A Background

    Gene Summary: Heat shock 70 kDa protein 1 is a protein that in humans is encoded by the HSPA1A gene. This intronless gene encodes a 70kDa heat shock protein which is a member of the heat shock protein 70 family. In conjuction with other heat shock proteins, this HSP72 protein stabilizes existing proteins against aggregation and mediates the folding of newly translated proteins in the cytosol and in organelles. HSP72 is also involved in the ubiquitin-proteasome pathway through interaction with the AU-rich element RNA-binding protein 1. The HSPA1A gene is located in the major histocompatibility complex class III region, in a cluster with two closely related genes which encode similar proteins.
    General information above from NCBI
    Subunit structure: Component of the CatSper complex (By similarity). Identified in a mRNP granule complex, at least composed of ACTB, ACTN4, DHX9, ERG, HNRNPA1, HNRNPA2B1, HNRNPAB, HNRNPD, HNRNPL, HNRNPR, HNRNPU, HSPA1, HSPA8, IGF2BP1, ILF2, ILF3, NCBP1, NCL, PABPC1, PABPC4, PABPN1, RPLP0, RPS3, RPS3A, RPS4X, RPS8, RPS9, SYNCRIP, TROVE2, YBX1 and untranslated mRNAs. Interacts with TSC2. Interacts with IRAK1BP1. Interacts with TERT; the interaction occurs in the absence of the RNA component, TERC, and dissociates once the TERT complex has formed. Interacts with DNAJC7. Interacts with CHCHD3. Interacts with TRIM5 (via B30.2/SPRY domain).
    Subcellular location: Cytoplasm. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs.
    Tissue specificity: HSPA1B is testis-specific.
    Induction: By heat shock.
    Sequence similarity: Belongs to the heat shock protein 70 family.
    General information above from UniProt

    HSPA1A is a member of the Hsp70 protein family. The 70 kilodalton heat shock proteins (Hsp70s) are a family of ubiquitously expressed heat shock proteins. HSP are abundant and conserved proteins present in all cells. Upon temperature shock or other stress stimuli, HSP are synthesized intracellularly, which may protect cells from protein denaturation or from death. Extracellularly, HSP can serve a cytokine function to initiate both innate and adaptive immunity through activation of APC. HSP serves also a chaperone function and facilitates presentation of antigen peptide to T cells. Molecular chaperones of the Hsp70 family have diverse functions in cells. They assist the folding of newly synthesized and stress-denatured proteins, as well as the import of proteins into organelles, and the dissociation of aggregated proteins. The well-conserved Hsp70 chaperones are ATP dependent: binding and hydrolysis of ATP regulates their interactions with unfolded polypeptide substrates, and ATPase cycling is necessary for their function. All cellular functions of Hsp70 chaperones use the same mechanism of ATP-driven polypeptide binding and release.
