Autocrine motility factor receptor, isoform 2 is a protein that in humans is encoded by the AMFR gene.[1][2]

Autocrine motility factor is a tumor motility-stimulating protein secreted by tumor cells. The protein encoded by this gene is a glycosylated transmembrane protein and a receptor for autocrine motility factor. The receptor, which shows some sequence similarity to tumor protein p53, is localized to the leading and trailing edges of carcinoma cells.[2]

Model organisms[edit]

Model organisms have been used in the study of AMFR function. A conditional knockout mouse line, called Amfrtm1a(KOMP)Wtsi[7][8] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[9][10][11]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[5][12] Twenty six tests were carried out on mutant mice and one significant abnormality was observed: Fewer than expected homozygous mutant mice survived until weaning.[5]


AMFR has been shown to interact with Valosin-containing protein.[13][14]
