VAB1 ATPase, V1 complex, subunit B protein [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: VAB1
Official Full Name: ATPase, V1 complex, subunit B protein
Primary source: TAIR:AT1G76030
Locus tag: AT1G76030
See related: Araport:AT1G76030
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: AtVAB1; V-ATPase B subunit 1; VHA-B1
Summary: One of three genes encoding the vacuolar ATP synthase subunit B1. This subunit was shown to interact with the gene product of hexokinase1 (ATHXK1). This interaction, however, is solely restricted to the nucleus. The protein binds to and co-localizes with F-actin, bundles F-actin to form higher-order structure, and stabilizes actin filaments in vitro.
