MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Sterile alpha motifs (SAMs) in proteins such as SAMD4A are part of an RNA-binding domain that functions as a posttranscriptional regulator by binding to an RNA sequence motif known as the Smaug recognition element, which was named after the Drosophila Smaug protein (Baez and Boccaccio, 2005 [PubMed 16221671]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Mice homozygous for an ENU-induced allele exhibit leaness, myopathy and altered glucose metabolism. Mice homozygous for a spontaneous mutation exhibit kyphosis, abnormal gait, and decreased cortical bone thickness. [provided by MGI curators]
