General annotation (Comments)

Function

Chaperone. Isoform 2 may function as an endogenous inhibitory regulator of HSC70 by competing the co-chaperones.

Subunit structure

Interacts with HSPH1/HSP105. Interacts with IRAK1BP1 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 PACRG and TSC2. Interacts with BAG1. Interacts with SV40 VP1. Ref.11 Ref.12 Ref.13 Ref.14 Ref.16

Subcellular location

Cytoplasm. Melanosome. 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. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Ref.10 Ref.18 Ref.20

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. Ref.11

Post-translational modification

Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.15 Ref.17 Ref.19 Ref.21 Ref.22 Ref.24

Sequence similarities

Belongs to the heat shock protein 70 family.

Alternative products
