S100A13, Mouse (His)

S100A13 Protein, acting as a homodimer, facilitates the export of signal peptide-lacking proteins through an alternative pathway, binding two calcium ions and one copper ion per subunit. It is crucial for the copper-dependent stress-induced export of IL1A and FGF1, with the calcium-free form binding to phosphatidylserine-containing lipid vesicles. S100A13 is part of a copper-dependent multiprotein complex, interacting with FGF1, SYT1, and IL1A. S100A13 Protein, Mouse (His) is the recombinant mouse-derived S100A13 protein, expressed by E. coli , with N-His labeled tag.
