| 1315909 | BTN1A1 | butyrophilin subfamily 1 member A1 | 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] | 6 | 26500303 | 26510425 | Human | 41 | symbol , COSMIC , Human Proteome Map | gene, protein-coding, VALIDATED [RefSeq] |
