AtVAB2; F22I13.8; V-ATPase B subunit 2; VHA-B2
NCBI Protein Information
ATPase, V1 complex, subunit B protein
NCBI Summary
One of three genes encoding the vacuolar ATP synthase subunit B1. The protein binds to and co-localizes with F-actin, bundles F-actin to form higher-order structure, and stabilizes actin filaments in vitro.
