Broad substrate specificity ATP-binding cassette transporter ABCG2 (EC 7.6.2.2) (ATP-binding cassette sub-family G member 2) (Breast cancer resistance protein 1 homolog) (Urate exporter) (CD antigen CD338) |
DISRUPTION PHENOTYPE |
Mice lacking Abcg2 are born at the expected Mendelian ratio and do not display overt phenotype (PubMed:12429862). However, under specific housing conditions, they show phototoxic skin lesions induced by pheophorbide a, a porphyrin catabolite of chlorophyll found in their diet, that accumulates in mice plasma (PubMed:12429862). They also accumulate a red substance in their bile and display protoporphyria with an accumulation of protoporphyrin IX (PPIX) in erythrocytes (PubMed:12429862). Mice lacking Abcg2 present decreased elimination of some uremic toxins like indoxyl sulfate leading to their accumulation in plasma (PubMed:30042379). They also show reduced survival rate upon adenine-induced chronic kidney disease (PubMed:30042379). {ECO:0000269|PubMed:12429862, ECO:0000269|PubMed:30042379}. |
