Small effector of CDC42 protein 1; Probably involved in the organization of the actin cytoskeleton by acting downstream of CDC42, inducing actin filament assembly. Alters CDC42-induced cell shape changes. In activated T-cells, may play a role in CDC42-mediated F-actin accumulation at the immunological synapse. May play a role in early contractile events in phagocytosis in macrophages; Belongs to the CDC42SE/SPEC family.
Synonyms: CDC42SE1, Q9NRR8, Q9NRR8p, hQ9NRR8, SPEC1 ...
