[Term] id: PR:000035435 name: mitotic checkpoint serine/threonine-protein kinase BUB1 beta phosphorylated 4 (human) def: "A mitotic checkpoint serine/threonine-protein kinase BUB1 beta phosphorylated 4 in human. This phosphorylated form is observed in prophase, prometaphase, metaphase, anaphase, spindle depolymerization (nocodazole). This form is not observed when there is a lack of kinetochore tension (taxol). Ser-435, Ser-574 and Ser-720 could also be phosphorylated. Example: UniProtKB:O60566-1, Ser-543/Ser-670/Ser-1043, MOD:00046." [PMID:19015317, PMID:20016069, PRO:KER] comment: Category=organism-modification.
