  • like RNF123, is localized to the cytosol
  • tail-anchored ubiquitin-specific protease localized to the ER
  • basic FUNCTION
  • involved in the ubiquitin-dependent proteolytic pathway in conjunction with the 26S proteasome
  • deubiquitinating enzyme that regulates the stability of a cyclin-dependent kinase inhibitor and demonstrate that progression through G1 to S phase is, like the metaphase-anaphase transition, controlled in a hierarchical, multilayered fashion
  • rescues the ER-associated-degradation (ERAD) substrates CFTRDelta508 and TCR-alpha from proteasomal degradation
  • function on specific ERAD substrates
  • modulates transcription of major myofibrillar proteins and the ubiquitin system not only mediates the increased protein breakdown but is also involved in the decreased protein synthesis in atrophying skeletal muscle
  • positively regulates proliferation in fibroblasts by stabilizing RNF123, a ubiquitin ligase for CDKN1B
  • regulates hypoxia-inducible factor 1A (HIF1A) during hypoxia
  • only the ER-localized isoform of USP19 (USP19-ER) modulated myoblast fusion as well as the expression of myogenin and myofibrillar proteins, and these effects were also dependent on USP19 catalytic activity
  • USP19 is involved in human muscle wasting
  • possible function of USP19 in quality control of misfolded proteins by regulating their protein levels
  • USP19 is involved in the regulation of ERAD by controlling the stability of MARCHF6 via deubiquitination
  • dual functions of the USP19-BECN1 axis by balancing autophagy and the production of type IIFNs
  • USP19 is a key factor in modulating DNA damage repair by targeting HDAC1/2 K63-linked ubiquitination
  • USP19 is an important regulator of fat development

    INTERACTION

    protein
  • interacting with and stabilizing RNF123
  • USP19, a deubiquitinating enzyme, interacts with cellular BIRC2, BIRC3
  • interacts with components of the hypoxia pathway including HIF1A and rescues it from degradation independent of its catalytic activity
  • SIAH1 and SIAH2 are binding partners of USP19, interaction mediated by a SIAH-consensus binding motif and promoting USP19 ubiquitylation and proteasome-dependent degradation
  • regulation of CORO2A through the deubiquitinating activity of USP19 affected the transcriptional repression activity of the retinoic acid receptor (RAR), suggesting that USP19 may be involved in the regulation of RAR-mediated adipogenesis
  • USP19 is the only deubiquitinase that directly binds to SIAHs(SIAH1, SIAH2) through the substrate binding pocket
  • USP19 regulates the stability of SYVN1 and provide insight into the regulatory mechanism of the ERAD ubiquitin ligases
  • DNAJC5 facilitates USP19-dependent unconventional secretion of misfolded cytosolic proteins
  • mechanistically, USP19 interacted with MAP3K7 in a TNF or IL1B-dependent manner
  • USP19 interacts with TICAM1 and catalyzes the removal of TICAM1 K27-linked polyubiquitin moieties, thereby impairing the recruitment of TICAM1 to TLR3/4
