Bcl6B, also known as BAZF, plays important roles in the immune response, repression of cancers, and maintenance of spermatogonial stem cells in mammals. In this study, the homologous gene bcl6b and its 5 alternative splicing variants, namely bcl6bX1 to bcl6bX5, were isolated from medaka fish, Oryzias latipes. Medaka bcl6b possesses conserved domains such as BTB domain, RD2 domain and four zinc fingers. Medaka bcl6bX1 to bcl6bX3 possess all three previously mentioned domains with minor differences in sequences. Medaka bcl6bX4 possesses only the BTB domain due to premature stopping, and bcl6bX5 ...
