UniProt functional annotation for Q8TF42



	UniProt functional annotation for Q8TF42

UniProt code: Q8TF42.

Organism: Homo sapiens (Human).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

Function: Interferes with CBL-mediated down-regulation and degradation of receptor-type tyrosine kinases. Promotes accumulation of activated target receptors, such as T-cell receptors and EGFR, on the cell surface. Exhibits tyrosine phosphatase activity toward several substrates including EGFR, FAK, SYK, and ZAP70. Down-regulates proteins that are dually modified by both protein tyrosine phosphorylation and ubiquitination. {ECO:0000269|PubMed:15159412, ECO:0000269|PubMed:17880946}.

Catalytic activity: Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] + phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA- COMP:10137, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474, ChEBI:CHEBI:46858, ChEBI:CHEBI:82620; EC=3.1.3.48; Evidence={ECO:0000269|PubMed:17880946};

Subunit: Homodimer. Interacts with JAK2 (in vitro) (By similarity). Interacts with CBL (PubMed:15159412). Part of a complex containing CBL and activated EGFR (PubMed:15159412). Interacts with ubiquitin and with mono-ubiquitinated proteins (PubMed:15159412). Interacts with ZAP70 (ubiquitinated form) (PubMed:26903241). {ECO:0000250|UniProtKB:Q8BGG7, ECO:0000269|PubMed:15159412, ECO:0000269|PubMed:26903241}.

Subcellular location: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000305}.

Sequence caution: Sequence=AAL16953.1; Type=Erroneous initiation; Evidence={ECO:0000305}; Sequence=BAB85545.1; Type=Erroneous initiation; Evidence={ECO:0000305};
