NCIt definition : E3 ubiquitin-protein ligase AMFR (643 aa, 75 kDa) is encoded by the human AMFR gene.
This protein plays a role in endoplasmic reticulum-associated degradation, protein
polyubiquitination, and autocrine motility factor binding.;
NCIt note : Secreted by tumor cells, autocrine motility factor stimulates tumor motility. Its
glycoprotein receptor, Autocrine Mobility Factor Receptor, has some homology to p53.
In normal fibroblasts, receptor expression appears to be regulated by cell-cell contact.
The level of expression is associated with the pathologic stage and grade of tumor
penetration. Positive AMFR expression on tumor cells correlates with poor prognosis
in bladder cancer. (from OMIM 603243 and NCI);
