Cationic amino acid transport permease (IPR004755)

Short name: Cat_AA_permease

Overlapping homologous superfamilies


Family relationships


Amino acid permeases are integral membrane proteins involved in the transport of amino acids into the cell. A number of such proteins have been found to be evolutionary related [PMID: 3146645, PMID: 2687114, PMID: 8382989]. These proteins seem to contain up to 12 transmembrane segments. The best conserved region in this family is located in the second transmembrane segment.

Proteins in this family are permeases involved in the transport of arginine, lysine and ornithine, the cationic amino acids.
