Domain

Stomatal closure-related actin-binding protein, actin-binding domain (IPR032012)

Short name: SCAB-ABD

Overlapping homologous superfamilies

None.

Domain relationships

None.

Description

This entry represents the actin-binding domain (ABD) of plant-specific actin-binding proteins or SCABs. SCAB proteins bind, bundle and stabilise actin filaments and regulate stomatal movement. The Ig-PH fusion domain is at the C terminus. The ABD is structurally independent from the first coiled-coil, CC1, domain which is also involved in binding; the CC1 is likely to function as a dimerisation module [PMID: 22356912],
