TIC40 — Pisum sativum

Summary

PsTIC40, encoded by PSAT5G144880 on chromosome 5LG3 of garden pea, is a transmembrane signaling receptor with ATP-dependent peptidase, GTPase, ATP hydrolase, mRNA binding, protein homodimerization, ATP binding, and protein binding activities, and belongs to the RPN13_DEUBAD_sf, STI1/HOP_DP, and STI1_HS-bd domain families. It is associated with the Tic complex, TOC-TIC supercomplex I, plastid stroma, chloroplast membranes, and envelope. The gene is associated with protein import into chloroplasts, regulation of photosynthesis and chlorophyll biosynthesis, de-etiolation, response to heat and salinity, embryo development, and seed viability. It is linked to leaf chlorophyll content, variegated leaf, linolenic and oleic acid content, photosynthetic ability, drought tolerance, root morphology, and arsenic concentration. Related genes in other species link the family to seed development, fertility, and albinism.
