CPB — Solanum tuberosum

Summary

StCPB, encoded by the potato gene PGSC0003DMG400016963 on chromosome 12, is an F-actin-capping protein subunit beta (CapZ beta). The gene product binds actin and F-actin, and is associated with actin filament capping, organization, and cytoskeleton organization. It is associated with cell morphogenesis, secondary metabolism, and digestion. StCPB has been linked to defense responses, including response to host and response to heat. The protein localizes to the cytoplasm and the F-actin capping protein complex. Studies of related genes in other species connect the family to thermotolerance and root development traits.
