  • two cytosolic nucleotide-binding domains (NBD1 and NBD2), dimerizing to form composite nucleotide binding sites (NBSs) each containing Walker A and B motifs from one domain and the ABC "C" signature from the other
  • 17 putative transmembrane (TM) helices forming three membrane-spanning domains (de Foresta 2010), are linked by extracellular and cytoplasmic loops (multiple roles for cytoplasmic loops 5 in the membrane expression and function of ABCC1)
  • two ATP binding (nucleotide binding fold)
  • one in the N terminus not found in most other ABC transporter
  • two membrane spanning domains (MSDs) each
  • a nucleotide binding domain
  • a third MSD with five transmembrane (TM) helices, whereas MSD2 and MSD3 each contain six TM helices
  • proline residues in the core cytoplasmic
  • transmembrane regions important for transport function, substrate specificity, and nucleotide interactions
  • secondary structure
  • broadly conserved helix-sheet-sheet-helix-helix structure
  • alpha-helices extending from TM9 and TM10 into the cytoplasm are linked by a stretch of amino acids (AAs 507
  • 521) that comprise the CL5 interface with NBD2 and also contain the so-called
    coupling helix,
    which is presumably initiated by Gly511
    interspecies homolog to murine Abcc1a

  • ABCC family
  • conjugate transporter subfamily
  • CATEGORY signaling , transport carrier
    SUBCELLULAR LOCALIZATION     plasma membrane
  • integral membrane protein
  • localized in cholesterol-enriched lipid rafts, which suggests a role for these lipid rafts and/or cholesterol in ABCC1 function
  • basic FUNCTION
  • ATP-binding cassette transporter that confers resistance to drugs(colchicine doxorubicine) and mediates the transport of organic anions
  • glutathione (GSH) cce protein ()onjugate (GS-x) pump or multispecific anion transporter
  • having specific biologic functions in epidermal lipid reorganization during terminal keratinocyte differentiation
  • playing a role in export of sphingosine-1-phosphate from mast cells
  • may play an important role in smoking-related lung function loss and development of chronic obstructive pulmonary disease (COPD)
  • with P-glycoprotein (ABCB1) and the breast cancer resistance protein (ABCG2), confers resistance to a large number of structurally diverse drugs
  • ability to mediate ATP-dependent CBL transport and having a physiologic role in CBL homeostasis
  • mediates the ATP-dependent efflux of a variety of organic anions derived from both endogenous metabolites and exogenous xenobiotics, many of which are conjugated to glutathione
  • its activity is not correlated with the level of free cholesterol or with localization in cholesterol-dependent lipid rafts
