FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Butyrophilin is the major protein associated with fat droplets in the milk. It is a member of the immunoglobulin superfamily. It may have a cell surface receptor function. The human butyrophilin gene is localized in the major histocompatibility complex (MHC) class I region of 6p and may have arisen relatively recently in evolution by the shuffling of exons between 2 ancestral gene families [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mice display impaired lactation and abnormal lipid accumulation in the mammary gland. [provided by MGI curators]
