Function
S100A2 is an EF-hand Ca2+-binding S100 protein that localizes in keratinocyte cytoplasm and nucleus, forms dimers, and undergoes oxidative cross-linking[1]. Mechanistically, S100A2 interacts with p53 in a Ca2+-dependent manner and increases p53 transcriptional activity, linking calcium signaling to cell-cycle control[2]. BRCA1 and p63 also coregulate S100A2, connecting this isoform to mutant p53 stability in breast cancer models[3]. In epithelial cancer models, S100A2 restrains squamous carcinoma cell motility through actin microfilament dynamics, supporting a tumor-suppressive migration phenotype[4]. In pancreatic cancer, however, S100A2 promotes EMT and metastasis through TGF-β/SMAD4 signaling, showing context-dependent disease relevance[5]. Compared with related S100 isoforms such as S100A4, S100A2 shows distinct expression and target-gene patterns in lung adenocarcinoma, making isoform-specific analysis essential[6]. For experimental applications, 3,5-bis (trifluoromethyl) benzene sulfonamides and 1,2,3-triazoles have been designed as small-molecule leads targeting the S100A2-p53 interaction in pancreatic cancer cell studies[7][8].

Expression
Tissue_specificity:A subset of epithelial cells including normal human mammary epithelial cells and keratinocytes
Induction:By growth factors in early G1 phase and probably by cell-cycle regulation in S phase. DNA methylation probably plays a direct negative role in suppressing S100L gene expression in tumor cells -
Subunit
Homodimer. Interacts with FKBP4. Interacts with PPP5C (via TPR repeats); the interaction is calcium-dependent and modulates PPP5C activity. Interacts with TPPP; this interaction inhibits TPPP dimerization (PubMed:33831707)
