Western blot analysis of extracts from Hela (lane 2(20μg) and Hela (lane 3(40μg)using PARP1 (HY-P80317) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% defatted milk powder in TBST for 2 hour at room temperature. The primary antibody (HY-P80317, 1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% defatted milk powder in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.

Immunohistochemical analysis of paraffin-embedded Mouse lung tissue using S100A4 Antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80317, 1/100) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX. -

Immunocytochemistry analysis of MCF-7 cells labeling S100A4 with S100A4 antibody(HY-P80317)at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with S100A4 antibody (HY-P80317) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L(HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue). -

Background
-
Function
S100A4 is a member of the S100 family of low molecular weight calcium-binding proteins that modulate intracellular and extracellular signaling processes[1]. Mechanistically, S100A4 interacts with cytoskeletal elements, including actin and non-muscle myosin, to regulate cell motility, migration, and invasion, contributing to tissue remodeling and metastasis[2][3]. In disease models, S100A4 expression is elevated in fibrotic tissues, various cancers, and neurological disorders, where it promotes progression by activating RAGE-mediated pathways and influencing epithelial-mesenchymal transition[1][3]. Compared with related isoforms such as S100A1 and S100B, S100A4 exhibits lower basal expression in normal tissues but higher inducibility under pathological stress, indicating isoform-specific regulation[1][4]. Experimental inhibition of S100A4 using small-molecule antagonists or peptide-based inhibitors suppresses motility and metastasis in vitro and in vivo, highlighting its utility as a target for translational research[1][5]. For experimental applications, S100A4 can serve as a biomarker for tumor aggressiveness and as a modulator of fibroblast and immune cell function in tissue remodeling assays[1][2]. Collectively, S100A4 represents a distinct functional isoform within the S100 family, integrating calcium-dependent signaling with cytoskeletal regulation and disease pathogenesis.

Subunit
Homodimer. Interacts with PPFIBP1 in a calcium-dependent mode (PubMed:11836260). Interacts with PGLYRP1; this complex acts as a chemoattractant that promotes lymphocyte movement (PubMed:26654597, PubMed:30713770). Interacts with MYH9; this interaction increases cell motility (PubMed:16707441). Interacts with Annexin 2/ANXA2 (PubMed:28669632). Interacts with TP53; this interaction promotes TP53 degradation (PubMed:23752197, PubMed:32442400). Interacts with CCR5 (PubMed:30713770). Interacts with FCGR3A; this interaction inhibits PKC-dependent phosphorylation of FCGR3A
