特記事項（精製）ab75599 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against the non-phosphopeptide was removed by chromatography using a non-phosphopeptide corresponding to the phosphorylation site.
機能The activated kinase acts on a variety of targets. Likely to be the GTPase effector that links the Rho-related GTPases to the JNK MAP kinase pathway. Activated by CDC42 and RAC1. Involved in dissolution of stress fibers and reorganization of focal complexes. Involved in regulation of microtubule biogenesis through phosphorylation of TBCB. Activity is inhibited in cells undergoing apoptosis, potentially due to binding of CDC2L1 and CDC2L2.
配列類似性Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily. Contains 1 CRIB domain. Contains 1 protein kinase domain.
翻訳後修飾Autophosphorylated when activated by CDC42/p21 and RAC1.
細胞内局在Cytoplasm. Cell junction > focal adhesion. Recruited to focal adhesions upon activation.
