Predicted to enable several functions, including calcium-dependent protein binding activity; protein homodimerization activity; and transmembrane transporter binding activity. Acts upstream of or within positive regulation of binding activity. Is extrinsic component of plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Orthologous to human S100A10 (S100 calcium binding protein A10). [provided by Alliance of Genome Resources, Apr 2022]
