Domain

ABC transporter, transmembrane domain (IPR001140)

Short name: ABC_transptr_TM_dom

Domain relationships

Description

A variety of ATP-binding transport proteins have a six transmembrane helical region. They are all integral membrane proteins involved in a variety of transport systems. Members of this family include; the cystic fibrosis transmembrane conductance regulator (CFTR), bacterial leukotoxin secretion ATP-binding protein, multidrug resistance proteins, the yeast leptomycin B resistance protein, the mammalian sulphonylurea receptor and antigen peptide transporter 2. Many of these proteins have two such regions.

This domain represents a unit of six transmembrane helices. Many members of the ABC transporter family have two such regions.
