General annotation (Comments)

Function	Downstream effector molecule involved in the transmission of signals from tyrosine kinase receptors and small GTPases to the actin cytoskeleton. Promotes formation of actin filaments. Part of the WAVE complex that regulates lamellipodia formation. The WAVE complex regulates actin filament reorganization via its interaction with the Arp2/3 complex. Ref.1 Ref.9
Subunit structure	Binds actin and the Arp2/3 complex. Interacts with BAIAP2. Component of the WAVE2 complex composed of ABI1, CYFIP1/SRA1, NCKAP1/NAP1 and WASF2/WAVE2. Directly interacts with BRK1. Ref.1 Ref.4 Ref.5 Ref.7 Ref.9
Subcellular location	Cytoplasm › cytoskeleton By similarity. Cell projection › lamellipodium By similarity. Note: At the interface between the lamellipodial actin meshwork and the membrane By similarity.
Tissue specificity	Expressed in all tissues with strongest expression in placenta, lung, and peripheral blood leukocytes, but not in skeletal muscle. Ref.1
Domain	Binds and activates the Arp2/3 complex via the C-terminal domain. Interacts with actin via the WH2 domain. Ref.1 Ref.9
Sequence similarities	Belongs to the SCAR/WAVE family. Contains 1 WH2 domain.
