SFMBT1Scm-like with four mbt domains 1 is a protein that in humans is encoded by the SFMBT1 gene.FunctionThis gene shares high similarity with the Drosophila Scm gene. It encodes a protein which contains four malignant brain tumor repeat domains and may be involved in antigen recognition. . It encodes a transcriptional repressor protein. The SFMBT1 protein's interaction with cancers is unclear, but elevated levels have been recorded in some renal cancers.
