Glycophorin B (MNS blood group), also known as GYPB, is a human gene.cite web | title = Entrez Gene: GYPB glycophorin B (MNS blood group)| url =| accessdate = ] GYPB has also recently been designated CD235b (cluster of differentiation 235b).

summary_text = Glycophorins A (GYPA) and B (GYPB) are major sialoglycoproteins of the human erythrocyte membrane which bear the antigenic determinants for the MN and Ss blood groups. GYPB gene consists of 5 exons and has 97% sequence homology with GYPA from the 5' UTR to the coding sequence encoding the first 45 amino acids. In addition to the M or N and S or s antigens, that commonly occur in all populations, about 40 related variant phenotypes have been identified. These variants include all the variants of the Miltenberger complex and several isoforms of Sta; also, Dantu, Sat, He, Mg, and deletion variants Ena, S-s-U- and Mk. Most of the variants are the result of gene recombinations between GYPA and GYPB.cite web | title = Entrez Gene: GYPB glycophorin B (MNS blood group)| url =| accessdate = ]
