Summaries for CDC42BPB Gene

Entrez Gene Summary for CDC42BPB Gene

  • This gene encodes a member of the serine/threonine protein kinase family. The encoded protein contains a Cdc42/Rac-binding p21 binding domain resembling that of PAK kinase. The kinase domain of this protein is most closely related to that of myotonic dystrophy kinase-related ROK. Studies of the similar gene in rat suggested that this kinase may act as a downstream effector of Cdc42 in cytoskeletal reorganization. [provided by RefSeq, Jul 2008]

GeneCards Summary for CDC42BPB Gene

CDC42BPB (CDC42 Binding Protein Kinase Beta (DMPK-Like)) is a Protein Coding gene. Diseases associated with CDC42BPB include myotonic dystrophy. GO annotations related to this gene include protein serine/threonine kinase activity and magnesium ion binding. An important paralog of this gene is STK38L.

UniProtKB/Swiss-Prot for CDC42BPB Gene

  • Serine/threonine-protein kinase which is an important downstream effector of CDC42 and plays a role in the regulation of cytoskeleton reorganization and cell migration. Regulates actin cytoskeletal reorganization via phosphorylation of PPP1R12C and MYL9/MLC2. In concert with MYO18A and LURAP1, is involved in modulating lamellar actomyosin retrograde flow that is crucial to cell protrusion and migration. Phosphorylates PPP1R12A.

    • Homodimer and homotetramer via the coiled coil regions. Interacts tightly with GTP-bound but not GDP-bound CDC42. Interacts with TJP1, when in the presence of catalytically active CDC42 (By similarity). Forms a tripartite complex with MYO18A and LURAP1 with the latter acting as an adapter connecting CDC42BPB and MYO18A. LURAP1 binding results in activation of CDC42BPB by abolition of its negative autoregulation.

Function for CDC42BPB Gene

Molecular function for CDC42BPB Gene

GENATLAS Biochemistry: CDC42-binding protein kinase beta,rat myotonic dystrophy protein kinase related (DMPK-like),beta (MRCKB),widely expressed,phosphorylating non muscle myosin like chain (see MYLK),a prerequisite for the activation of actin-myosin contractility,downstream effector of CDC42 in cytoskeletal reorganization
UniProtKB/Swiss-Prot CatalyticActivity: ATP + a protein = ADP + a phosphoprotein.
UniProtKB/Swiss-Prot EnzymeRegulation: Maintained in an inactive, closed conformation by an interaction between the kinase domain and the negative autoregulatory C-terminal coiled-coil region. Agonist binding to the phorbol ester binding site disrupts this, releasing the kinase domain to allow N-terminus-mediated dimerization and kinase activation by transautophosphorylation (By similarity). Inhibited by chelerythrine chloride.
UniProtKB/Swiss-Prot Function: Serine/threonine-protein kinase which is an important downstream effector of CDC42 and plays a role in the regulation of cytoskeleton reorganization and cell migration. Regulates actin cytoskeletal reorganization via phosphorylation of PPP1R12C and MYL9/MLC2. In concert with MYO18A and LURAP1, is involved in modulating lamellar actomyosin retrograde flow that is crucial to cell protrusion and migration. Phosphorylates PPP1R12A.
