The HLA class II region contains at least 3 groups of loci, DR, DC and SB, which play an important role in the immune response [isolated from human B cells]. the antigens encoded at these loci are heterodimers composed of an .alpha. and .beta. chain. The sequence of a complete class II .beta. cDNA clone whose sequence agrees closely with the limited N-terminal protein sequence available for the SB.beta. chain is reported. In addition the structure and coding sequence of genomic SB.beta. clones of 2 different SB haploytypes has been obtained and allows definition of some polymorphic regions. The SB.beta. gene appears to undergo alternate splicing at its 3' end, resulting in expression of 2 different intracytoplasmic regions. Partial sequencing of a 2nd non-allelic SB.beta.-like gene, SX.beta., indicates that it is a psudogene.
