O1 — Camelina sativa

Summary

CSA18G009960 (symbol O1, also known as CsMYA2) encodes a protein with domains including a myosin head motor domain, IQ motifs, and a dilute domain. The gene product exhibits microfilament motor activity, calmodulin binding, and small GTPase binding, and is associated with actin filament-based movement, actin filament organization, and organelle localization including peroxisome, mitochondria, and Golgi. It is associated with leaf pavement cell development, trichome morphogenesis, pistil development, and defense response. Associations with plant cell shape, stem elongation, root hair elongation, polar auxin transport, fertility, trichome branching, cell expansion, and organelle motility have been reported. Related genes in other species are linked to cytoplasmic streaming, auxin transport, and post-embryonic development. The protein localizes to the myosin complex, actin cytoskeleton, Golgi membrane, and trans-Golgi network membrane.
