Band_3_cyto

Band_3_cyto
PFAM accession number:PF07565
Interpro abstract (IPR013769):

This entry contains the cytoplasmic domain of the Band 3 anion exchange proteins that exchange Cl-/HCO3-. Band 3 constitutes the most abundant polypeptide in the red blood cell membrane, comprising 25% of the total membrane protein. The cytoplasmic domain of band 3 functions primarily as an anchoring site for other membrane-associated proteins. Included among the protein ligands of cdb3 are ankyrin, protein 4.2, protein 4.1, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), phosphofructokinase, aldolase, hemoglobin, hemichromes, and the protein tyrosine kinase (p72syk) [(PUBMED:11049968)].

GO process:anion transport (GO:0006820)
GO component:integral component of membrane (GO:0016021)
GO function:anion transmembrane transporter activity (GO:0008509)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Band_3_cyto
