title: PL48: a novel gene associated with cytotrophoblast and lineage-specific HL-60 cell differentiation.
abstract: The cDNA for a novel gene, PL48, isolated by subtractive hybridization between undifferentiated human term cytotrophoblast and differentiating cytotrophoblast, has been cloned and sequenced. PL48 contains an open reading frame coding for a 537-amino acid protein, has multiple potential PKC, casein kinase II, and cAMP/cGMP-dependent kinase phosphorylation sites, and N-linked glycosylation sites. It is not present in a wide variety of proliferating cancer cells, but PL48 mRNA shows marked expression during cytotrophoblast and granulocyte lineage-specific HL-60 promyelocytic cell differentiation induced by DMSO.
