Sterile Alpha Motif Domain Containing Protein 10 (SaMD10)

SaMD10, Contains 1 SAM (sterile alpha motif) domain. May play a role in atherogenesis by immobilizing LDL in the atherial wall.The sterile alpha motif (SAM) domain is a protein module found in many diverse signaling proteins. SAM domains in some systems have been shown to self-associate. Previous crystal structures of an EphA4-SAM domain dimer and a possible EphB2-SAM oligomer both revealed large interfaces comprising an exchange of N-terminal peptide arms. Within the arm, a conserved hydrophobic residue is anchored into a hydrophobic cleft on a neighboring molecule. A new crystal form of the human EphB2-SAM domain that has the same overall SAM domain fold yet has no substantial intermolecular contacts.
