Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

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 (PubMed:21457715, PubMed:21949762).

In concert with MYO18A and LURAP1, is involved in modulating lamellar actomyosin retrograde flow that is crucial to cell protrusion and migration (PubMed:18854160).

Phosphorylates PPP1R12A (PubMed:21457715).

In concert with FAM89B/LRAP25 mediates the targeting of LIMK1 to the lamellipodium resulting in its activation and subsequent phosphorylation of CFL1 which is important for lamellipodial F-actin regulation (By similarity).

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.By similarity1 Publication

Homodimer and homotetramer via the coiled coil regions (PubMed:21949762).

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 (PubMed:18854160).

Interacts with STRIP1, STRN3 and SIKE1 (PubMed:25743393).

Interacts with CPNE4 (via VWFA domain).

Interacts with LURAP1.

Interacts (via AGC-kinase C-terminal domain) with FAM89B/LRAP25 (via LRR repeat).

Forms a tripartite complex with FAM89B/LRAP25 and LIMK1 (By similarity).

<p>The checksum is a form of redundancy check that is calculated from the sequence.
