This gene encodes a predicted transmembrane protein containing two extracellular CUB domains followed by a low-density lipoprotein class A (LDLa) domain. It also has an intracellular FXNPXY-like motif, which has been shown in other proteins to be essential for the internalization of clathrin coated pits during endocytosis. Alternatively spliced transcript variants have been observed, but they have not been fully characterized. [provided by RefSeq].
