ABC transporter transmembrane domain is the main transmembrane structural unit of ATP-binding cassette transporter proteins, consisting of six alpha helixes that traverse the plasma membrane. Many members of the ABC transporter family (Pfam PF00005) have two such regions.[1][2][3][4][5][6]
This family appears to correspond to ABC1 by TCDB classification.
