Although several class II promoter-specific DNA binding factors have been described , only the X box region factor , RFX , shows a genetic correlation with class II expression , being deficient in some B cell lines derived from patients with class II-deficient congenital immunodeficiency .
although several class ii promoter-specific dna binding factors have been described , only the x box region factor , rfx , shows a genetic correlation with class ii expression , being deficient in some b cell lines derived from patients with class ii-deficient congenital immunodeficiency .
