BR1 — Brassica oleracea

Summary

BoBR1 (BOLC102_C01P007400.1) on cabbage chromosome 1 encodes a member of the MCP (mitochondrial carrier protein) family with MCP_transmembrane and MCP_dom_sf domains. The gene product exhibits nucleotide transmembrane transporter activity, coenzyme A transmembrane transporter activity, thiamine diphosphate transporter activity, thiamin permease activity, ATP/ADP exchange activity, and ATP binding. BoBR1 is associated with nucleotide transport, tropism, regulation of mitochondrial membrane permeability, mitochondrial coenzyme A and ATP/ADM transmembrane transport, TPP transport, purine nucleotide-sugar membrane transport, glucosinolate and chlorophyll anabolism, and embryo development ending in seed dormancy. It localizes to the mitochondrial inner membrane, chloroplast inner membrane and envelope, amyloplast inner membrane, plastid, plasmalemma, and the MPTP complex. The gene is linked to chlorophyll content, plant growth, sugar sensitivity, salt tolerance, cold stress tolerance, ABA sensitivity, fertility, seed fertility, and stress response. Related genes in other species connect the family to embryo development and mitochondrial transport.
