TIC20 — Pisum sativum

Summary

PSAT7G252800 (symbol TIC20) on chromosome 7LG7 encodes a Tic20 family protein with transmembrane protein transporter activity and protein binding. The product localises to the chloroplast inner membrane and is associated with protein import, protein secretion, and regulation of photosynthesis, including downregulation of photosynthesis. The gene has been connected to chloroplast development, protein import across the chloroplast inner envelope membrane, and phenotypes including partial complementation, abnormal growth, and impaired greening. Related genes in other species link the TIC20 family to chloroplast development traits, photochemical quenching, and phenotypes such as irregular leaf development with variable growth arrest and albino seedlings with anthocyanin accumulation.
