Human Gene HSPA8 (ENST00000453788.6) from GENCODE V44
  Description: Homo sapiens heat shock protein family A (Hsp70) member 8 (HSPA8), transcript variant 2, mRNA. (from RefSeq NM_153201)
RefSeq Summary (NM_153201): This gene encodes a member of the heat shock protein 70 family, which contains both heat-inducible and constitutively expressed members. This protein belongs to the latter group, which are also referred to as heat-shock cognate proteins. It functions as a chaperone, and binds to nascent polypeptides to facilitate correct folding. It also functions as an ATPase in the disassembly of clathrin-coated vesicles during transport of membrane components through the cell. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011].

  ID: HSP7C_HUMAN
DESCRIPTION: RecName: Full=Heat shock cognate 71 kDa protein; AltName: Full=Heat shock 70 kDa protein 8;
FUNCTION: Acts as a repressor of transcriptional activation. Inhibits the transcriptional coactivator activity of CITED1 on Smad-mediated transcription. Chaperone. Component of the PRP19- CDC5L complex that forms an integral part of the spliceosome and is required for activating pre-mRNA splicing. May have a scaffolding role in the spliceosome assembly as it contacts all other components of the core complex.
SUBUNIT: 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 PACRG. Interacts with HSPH1/HSP105. Interacts with IRAK1BP1 and BAG1. Interacts with DNAJC7. Interacts with CITED1 (via N- terminus); the interaction suppresses the association of CITED1 to p300/CBP and Smad-mediated transcription transactivation. Component of the PRP19-CDC5L splicing complex composed of a core complex comprising a homotetramer of PRPF19, CDC5L, PLRG1 and BCAS2, and at least three less stably associated proteins CTNNBL1, CWC15 and HSPA8. Interacts with SV40 VP1.
INTERACTION: P60709:ACTB; NbExp=2; IntAct=EBI-351896, EBI-353944; P49407:ARRB1; NbExp=4; IntAct=EBI-351896, EBI-743313; P32121:ARRB2; NbExp=4; IntAct=EBI-351896, EBI-714559; Q9UNE7:STUB1; NbExp=3; IntAct=EBI-351896, EBI-357085;
SUBCELLULAR LOCATION: Cytoplasm. Melanosome. Nucleus, nucleolus. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Translocates rapidly from the cytoplasm to the nuclei, and especially to the nucleoli, upon heat shock.
TISSUE SPECIFICITY: Ubiquitous.
INDUCTION: Constitutively synthesized.
DOMAIN: The N-terminal 1-386 residues constitute the ATPase domain, while residues 387-646 form the peptide-binding domain.
PTM: Acetylated.
PTM: Phosphorylated upon DNA damage, probably by ATM or ATR.
PTM: ISGylated.
SIMILARITY: Belongs to the heat shock protein 70 family.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
