Protein Information (annotations from UniProt)

Database IDHIV0009749
UniProt IDQ9Y297
Primary gene name(s)BTRC
Synonym gene name(s)BTRCP, FBW1A, FBXW1A
Protein nameF-box/WD repeat-containing protein 1A
Protein functionSubstrate recognition component of a SCF, SKP1-CUL1-F-box protein E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Recognizes and binds to phosphorylated target proteins. SCF(BTRC mediates the ubiquitination of CTNNB1 and participates in Wnt signaling. SCF(BTRC mediates the ubiquitination of NFKBIA, NFKBIB and NFKBIE; the degradation frees the associated NFKB1 to translocate into the nucleus and to activate transcription. Ubiquitination of NFKBIA occurs at 'Lys-21' and 'Lys-22'. SCF(BTRC mediates the ubiquitination of CEP68; this is required for centriole separation during mitosis, PubMed:25704143, PubMed:25503564. SCF(BTRC mediates the ubiquitination of phosphorylated NFKB1/nuclear factor NF-kappa-B p105 subunit, ATF4, CDC25A, DLG1, FBXO5, PER1, SMAD3, SMAD4, SNAI1 and probably NFKB2. Has an essential role in the control of the clock-dependent transcription via degradation of phosphorylated PER1 and PER2. May be involved in ubiquitination and subsequent proteasomal degradation through a DBB1-CUL4 E3 ubiquitin-protein ligase. Required for activation of NFKB-mediated transcription by IL1B, MAP3K14, MAP3K1, IKBKB and TNF. Required for proteolytic processing of GLI3. {ECO:0000269|PubMed:10066435, ECO:0000269|PubMed:10497169, ECO:0000269|PubMed:10644755, ECO:0000269|PubMed:10835356, ECO:0000269|PubMed:11238952, ECO:0000269|PubMed:11359933, ECO:0000269|PubMed:11994270, ECO:0000269|PubMed:12791267, ECO:0000269|PubMed:12902344, ECO:0000269|PubMed:14603323, ECO:0000269|PubMed:14681206, ECO:0000269|PubMed:14988407, ECO:0000269|PubMed:15448698, ECO:0000269|PubMed:15917222, ECO:0000269|PubMed:16371461, ECO:0000269|PubMed:25503564, ECO:0000269|PubMed:25704143, ECO:0000269|PubMed:9859996}.
