Anti-Cullin 5/CUL-5 antibody

Target data

Core component of multiple cullin-5-RING E3 ubiquitin-protein ligase complexes (ECS complexes, also named CRL5 complexes), which mediate the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed : 11384984, PubMed : 15601820, PubMed : 21199876, PubMed : 21980433, PubMed : 23897481, PubMed : 25505247, PubMed : 27910872, PubMed : 32200094, PubMed : 33268465, PubMed : 35512830, PubMed : 38418882). Acts a scaffold protein that contributes to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme (PubMed : 11384984, PubMed : 15601820, PubMed : 33268465). The functional specificity of the E3 ubiquitin-protein ligase complex depends on the variable SOCS box-containing substrate recognition component (PubMed : 11384984, PubMed : 15601820, PubMed : 33268465). Acts as a key regulator of neuron positioning during cortex development : component of various SOCS-containing ECS complexes, such as the ECS(SOCS7) complex, that regulate reelin signaling by mediating ubiquitination and degradation of DAB1 (By similarity). ECS(SOCS1) seems to direct ubiquitination of JAK2 (PubMed : 11384984). The ECS(SOCS2) complex mediates the ubiquitination and subsequent proteasomal degradation of phosphorylated EPOR and GHR (PubMed : 21980433, PubMed : 25505247). The ECS(SPSB3) complex catalyzes ubiquitination of nuclear CGAS (PubMed : 38418882). ECS(KLHDC1) complex is part of the DesCEND (destruction via C-end degrons) pathway and mediates ubiquitination and degradation of truncated SELENOS selenoprotein produced by failed UGA/Sec decoding, which ends with a glycine (PubMed : 32200094). The ECS(ASB9) complex mediates ubiquitination and degradation of CKB (PubMed : 33268465). As part of some ECS complex, promotes 'Lys-11'-linked ubiquitination and degradation of BTRC (PubMed : 27910872). As part of a multisubunit ECS complex, polyubiquitinates monoubiquitinated POLR2A (PubMed : 19920177). As part of the ECS(RAB40C) complex, mediates ANKRD28 ubiquitination and degradation, thereby inhibiting protein phosphatase 6 (PP6) complex activity and focal adhesion assembly during cell migration (PubMed : 35512830). As part of the ECS(RAB40A) complex, mediates RHOU 'Lys-48'-linked ubiquitination and degradation, thus inhibiting focal adhesion disassembly during cell migration (PubMed : 26598620). As part of the ECS(RAB40B) complex, mediates LIMA1/EPLIN and RAP2 ubiquitination, thereby regulating actin cytoskeleton dynamics and stress fiber formation during cell migration (PubMed : 33999101, PubMed : 35293963). The ECS(ASB7) complex acts a negative regulator of H3K9me3 histone mark by mediating ubiquitination and degradation of SUV39H1 (PubMed : 40440427). May form a cell surface vasopressin receptor (PubMed : 9037604).. (Microbial infection) Following infection by HIV-1 virus, CUL5 associates with HIV-1 Vif proteins and forms a cullin-5-RING E3 ubiquitin-protein ligase complex (ECS complex) that catalyzes ubiquitination and degradation of APOBEC3F and APOBEC3G (PubMed : 16636053, PubMed : 22190037). The complex can also ubiquitinate APOBEC3H to some extent (PubMed : 37640699).. (Microbial infection) Seems to be involved in proteasomal degradation of p53/TP53 stimulated by adenovirus E1B-55 kDa protein.
