HSC70 / TRP channels
Name: Heat shock cognate 71 kDa protein
(HSC70)
Official Symbol: HSPA8
provided by HGNC
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.
