General annotation (Comments)

Function

Part of the WAVE complex that regulates lamellipodia formation. The WAVE complex regulates actin filament reorganization via its interaction with the Arp2/3 complex. Actin remodeling activity is regulated by RAC1.

Subunit structure

Component of the WAVE1 complex composed of ABI2, CYFIP1 or CYFIP2, BRK1, NCKAP1 and WASF1/WAVE1. Within the complex, a heterdimer containing NCKAP1 and CYFIP1 interacts with a heterotrimer formed by WAVE1, ABI2 and BRK1. Component of the WAVE2 complex composed of ABI1, CYFIP1/SRA1, NCKAP1/NAP1 and WASF2/WAVE2. CYFIP2 binds to activated RAC1 which causes the complex to dissociate, releasing activated WASF1. The complex can also be activated by NCK1. Associates preferentially with the first SH3 domain of NCK By similarity. Ref.8

Subcellular location

Cell membrane; Single-pass membrane protein; Cytoplasmic side By similarity. Cell projectionlamellipodium membrane; Single-pass membrane protein; Cytoplasmic side By similarity. Note: At the interface between the lamellipodial actin meshwork and the membrane By similarity.

Tissue specificity

Expressed in all tissues examined except peripheral blood leukocytes, with highest expression in brain, heart, and skeletal muscle.

Sequence similarities

Belongs to the HEM-1/HEM-2 family.

Sequence caution

The sequence BAA25513.2 differs from that shown. Reason: Erroneous initiation.
