NCIt synonyms : S-100L Protein; S100 Calcium-Binding Protein A2; S100A2; CAN19; Protein S-100L; S100 Calcium Binding Protein-A2;
NCIt definition : Protein S100-A2 (98 aa, 11 kDa) is encoded by the human S100A2 gene. This protein
plays a role in binding to calcium and to other proteins.;
NCIt note : Encoded by human S100A2 Gene, 97-amino acid 11 kD S-100L Protein is a member of the
S100 Family of cell specific Ca2 -binding proteins containing EF-hand calcium-binding
motifs. Induced by growth factors in early G1 and probably by cell-cycle regulation
in S phase, S100A2 is preferentially expressed in mammary epithelia and in keratinocytes.
S100 proteins are cytoplasmic or nuclear and involved in regulation of cell cycle
progression and differentiation. Containing two EF-hand calcium-binding domains, S100
Calcium-Binding Protein A2 interacts with target proteins to link extracellular stimuli
to cellular responses and may modulate excess calcium accumulation in mammary epithelial
cells. Altered expression of S100A2 has been implicated in breast cancer. (SwissProt
