General annotation (Comments)

Function	Inhibits the chaperone activity of HSP70/HSC70 by promoting substrate release. Inhibits the pro-apoptotic function of PPP1R15A, and has anti-apoptotic activity. Markedly increases the anti-cell death function of BCL2 induced by various stimuli. Ref.10 Ref.13 Ref.15
Subunit structure	Homodimer. Forms a heteromeric complex with HSP70/HSC70. Binds to the ATPase domain of HSP/HSC70 chaperones. Isoform 1, isoform 3 and isoform 4 but not isoform 2 interact with HSPA8/HSC70. Interacts with NR3C1. Interacts with the N-terminal region of STK19. Interacts with PPP1R15A. Interacts with BCL2 in an ATP-dependent manner. Isoform 2 does not interact with BCL2. Ref.4 Ref.10 Ref.11 Ref.12 Ref.14 Ref.15
Subcellular location	Isoform 1: Nucleus. Cytoplasm. Note: Isoform 1 localizes predominantly to the nucleus. Ref.4 Ref.11 Isoform 2: Cytoplasm. Nucleus. Note: Isoform 2 localizes to the cytoplasm and shuttles into the nucleus in response to heat shock. Ref.4 Ref.11 Isoform 4: Cytoplasm. Nucleus. Note: Isoform 4 localizes predominantly to the cytoplasm. The cellular background in which it is expressed can influence whether it resides primarily in the cytoplasm or is also found in the nucleus. In the presence of BCL2, localizes to intracellular membranes (what appears to be the nuclear envelope and perinuclear membranes) as well as punctate cytosolic structures suggestive of mitochondria. Ref.4 Ref.11
Tissue specificity	Isoform 4 is the most abundantly expressed isoform. It is ubiquitously expressed throughout most tissues, except the liver, colon, breast and uterine myometrium. Isoform 1 is expressed in the ovary and testis. Isoform 4 is expressed in several types of tumor cell lines, and at consistently high levels in leukemia and lymphoma cell lines. Isoform 1 is expressed in the prostate, breast and leukemia cell lines. Isoform 3 is the least abundant isoform in tumor cell lines (at protein level). Ref.11
Induction	Up-regulated during differentiation of bladder epithelial cells and down-regulated during differentiation of prostate epithelium. Ref.11
Post-translational modification	Ubiquitinated; mediated by SIAH1 or SIAH2 and leading to its subsequent proteasomal degradation Probable.
Sequence similarities	Contains 1 BAG domain. Contains 1 ubiquitin-like domain.
Sequence caution	The sequence AAD11467.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence AAD25045.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAD96469.1 differs from that shown. Reason: Unusual initiator. The initiator methionine is coded by a non-canonical CTG leucine codon. The sequence CAA84624.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence CAH72516.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAH72518.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAH72741.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAH72742.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence EAW58515.1 differs from that shown. Reason: Erroneous gene model prediction.
