FAMILY

CorA metal ion transporter (MIT) (TC 1.A.35) family

DESCRIPTION

Also known as CORA_METJA, corA. Mediates influx of magnesium ions (PubMed:9573171, PubMed:10748031). Alternates between open and closed states. Activated by low cytoplasmic Mg(2+) levels. Inactive when cytoplasmic Mg(2+) levels are high. Can also mediate Co(2+) uptake (By similarity). Homopentamer (PubMed:23091000, PubMed:26051127). In the absence of Mg(2+), interactions between subunits are weakened, and dimers, trimers and tetramers can be observed in vitro (By similarity). Was initially proposed to be a homotetramer, based on the cross-linking studies (PubMed:15231793). This is in contradiction with current 3D-structures that clearly show it is a homopentamer (PubMed:23091000, PubMed:26051127).
