Immunohistochemistry (IHC)
(MBS9606041 at 1/100 staining Human tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary.)
Subunit Structure: Interacts with UFD1. Interacts (via UBA domains) with SIAH2 (when ubiquitinated). Interacts with BAG6; the interaction is direct and may mediate UBL4A deubiquitination (PubMed:24424410). Interacts (via UBA 2 domain) with AMFR; the interaction is direct (PubMed:24424410). Interacts with UBL4A; may be indirect via BAG6 (PubMed:24424410).
Similarity: The UBP-type zinc finger has lost its ability to bind ubiquitin and USP13 is not activated by unanchored ubiquitin. Swapping with the UBP-type zinc finger from USP5 restores ability to bind unanchored ubiquitin and subsequent activation of the protein (PubMed:22216260).The UBA domains mediate binding to ubiquitin. Belongs to the peptidase C19 family.

Uniprot Description
Deubiquitinase that mediates deubiquitination of target proteins such as BECN1, MITF, SKP2 and USP10 and is involved in various processes such as autophagy and endoplasmic reticulum-associated degradation (ERAD). Component of a regulatory loop that controls autophagy and p53/TP53 levels: mediates deubiquitination of BECN1, a key regulator of autophagy, leading to stabilize the PIK3C3/VPS34-containing complexes. Also deubiquitinates USP10, an essential regulator of p53/TP53 stability. In turn, PIK3C3/VPS34-containing complexes regulate USP13 stability, suggesting the existence of a regulatory system by which PIK3C3/VPS34-containing complexes regulate p53/TP53 protein levels via USP10 and USP13. Recruited by nuclear UFD1 and mediates deubiquitination of SKP2, thereby regulating endoplasmic reticulum-associated degradation (ERAD). Also regulates ERAD through the deubiquitination of UBL4A a component of the BAG6/BAT3 complex. Mediates stabilization of SIAH2 independently of deubiquitinase activity: binds ubiquitinated SIAH2 and acts by impairing SIAH2 autoubiquitination. Has a weak deubiquitinase activity in vitro and preferentially cleaves 'Lys-63'-linked polyubiquitin chains. In contrast to USP5, it is not able to mediate unanchored polyubiquitin disassembly. Able to cleave ISG15 in vitro; however, additional experiments are required to confirm such data.
