Vaihtoehtoisesti
silmukoituneita transkriptivariantteja löydetään tästä
geenistä. Tätä lyhyttä proteiini-isoformia on havaittavissa vain
HIV-1 retroviruksella infektoituneissa soluissa. Geenillä on
synonyyminimiä HIN1, DUBA6, HSHIN1. Jo vuonna 1992 tutkijat
tekivät havainnon proteiinista, jota muodostui vain HIV1 viruksella
infektoituneista soluista. (”HIV-1 promotor insertion revealed by
selective detection of chimeric provirus-host-gene transcripts).
Pitemmässä variantissa on 1049 aminohappoa. Vaihtoehtoisnimi
proteiinille on HIV-1 viruksen indusoima proteiini HIN-1. Suositeltu
nimi on OTU-domeenin sisältävä proteiini 4. OTUD4 pidetään varsinaisesti K48
deubikitinaasina, mutta fosfoaktivoitu OTUD4 paljastaa sen latentin
K63-deubikitinaasipiirteen, joka säätelee MyD88:sta riippuvaa järjestelmää.
(MyD99 proteiini on tärkeänä adaptorina järjestelmässä, joka
tunnistaa soluun tulevia patogeenejä Tollin reseptoreilla).

PMID 1475186, Free PMC Article https://www.ncbi.nlm.nih.gov/pubmed/1475186/This shows for the first time that HIV-1 can activate transcription of host cellular genes by promotor insertion in a fashion similar to slow-transforming avian and murine retroviruses.

OTUD4 Is a Phospho-Activated K63 Deubiquitinase that Regulates MyD88-Dependent Signaling. Zhao Y, et al. Mol Cell, 2018 Feb 1. PMID 29395066 Ubiquitination is a major mechanism that regulates numerous cellular processes, including autophagy, DNA damage signaling, and inflammation. While hundreds of ubiquitin ligases exist to conjugate ubiquitin onto substrates, approximately 100 deubiquitinases (DUBs) are encoded by the human genome. Thus, deubiquitinases are likely regulated by unidentified mechanisms to target distinct substrates and cellular functions. Here, we demonstrate that the deubiquitinase OTUD4, which nominally encodes a K48-specific deubiquitinase, is phosphorylated near its catalytic domain, activating a latent K63-specific deubiquitinase. Besides phosphorylation, this latter activity requires an adjacent ubiquitin-interacting motif, which increases the affinity of OTUD4 for K63-linked chains. We reveal the Toll-like receptor (TLR)-associated factor MyD88 as a target of this K63 deubiquitinase activity. Consequently, TLR-mediated activation of NF-κB is negatively regulated by OTUD4, and macrophages from Otud4-/- mice exhibit increased inflammatory signaling upon TLR stimulation. Our results reveal insights into how a deubiquitinase may modulate diverse processes through post-translational modification.

OTUD4 is a positive regulator of ALKBH2 and ALKBH3, two DNA demethylases critical for alkylation repair. Repair of DNA alkylation damage is critical for genomic stability and involves multiple conserved enzymatic pathways. Alkylation damage resistance, which is critical in cancer chemotherapy, depends on the overexpression of alkylation repair proteins. However, the mechanisms responsible for this upregulation are unknown. Here, we show that an OTU domain deubiquitinase, OTUD4, is a positive regulator of ALKBH2 and ALKBH3, two DNA demethylases critical for alkylation repair. Remarkably, we find that OTUD4 catalytic activity is completely dispensable for this function. Rather, OTUD4 is a scaffold for USP7 and USP9X, two deubiquitinases that act directly on the AlkB proteins. Moreover, we show that loss of OTUD4, USP7, or USP9X in tumor cells makes them significantly more sensitive to alkylating agents. Taken together, this work reveals a novel, noncanonical mechanism by which an OTU family deubiquitinase regulates its substrates, and provides multiple new targets for alkylation chemotherapy sensitization of tumors.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4475402/
