The other major conserved integral membrane proteins of urothelial plaques are UPK1A (MIM 611557), UPK2 (MIM 611558), and UPK3A (MIM 611559) (Deng et al., 2002 [PubMed 12446744]).[supplied by OMIM, Mar 2008] Expression Biased expression in lung (RPKM 16.8), urinary bladder (RPKM 3.5) and 2 other tissues See more Orthologs mouse all
