General annotation (Comments)

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 By similarity.
Subunit structure	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 By similarity. Interacts with TRIM5 By similarity.
Subcellular location	Cytoplasm By similarity. Melanosome By similarity. Nucleus › nucleolus By similarity. 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 By similarity.
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 By similarity.
Post-translational modification	Acetylated By similarity. ISGylated By similarity.
Sequence similarities	Belongs to the heat shock protein 70 family.
