Sterile Alpha Motif Domain Containing Protein 13 (SaMD13)

SaMD13 Contains 1 SAM (sterile alpha motif) domain. The sterile alpha motif (SAM) domain is a putative protein interaction module present in a wide variety of proteins  involved in many biological processes. The SAM domain that spreads over around 70 residues is found in diverse eukaryotic organisms . SAM domains have been shown to homo- and hetero-oligomerise, forming multiple self-association architectures and also binding to various non-SAM domain-containing proteins, nevertheless with a low affinity constant. SAM domains also appear to possess the ability to bind RNA. Smaug, a protein that helps to establish a morphogen gradient in Drosophila embryos by repressing the translation of nanos (nos) mRNA, binds to the 3""" untranslated region (UTR) of nos mRNA via two similar hairpin structures.
