[5] This metastasis suppressor gene product is a membrane glycoprotein that is a member of the tetraspanin/transmembrane 4 superfamily.

Expression of this gene has been shown to be downregulated in tumor progression of human cancers and can be activated by p53 through a consensus binding sequence in the promoter.

Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.
