(Peptide available as ab41274.)

Reacts with 
(species key)

Hu, Ms, Rat

Specificity

Recommended dilutions
IHC-P: Use at an assay dependent dilution (PMID 18403594).
WB: 1/1000 when using colorimetric substrates such as BCIP/NBT - 1/5000 when using chemiluminescent substrates. Detects a band of approximately 110-120 kDa (predicted molecular weight: 88 kDa). Note: EDTA/EGTA treatment of tissues or lysates is required to see latent zymogen. Dilution optimised using Chromogenic detection.

Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.

Cellular localization 

Cell Membrane; single-pass type II membrane protein. Found in cell surface lamellipodia, invadopodia and on shed vesicles.

Relevance 

Fibroblast Activation Protein alpha subunit (FAPa or FAP, alpha) is a integral membrane gelatinase belonging to the serine protease family. FAPa is the alpha subunit and DPP4 (CD26) the beta subunit of a heterodimeric membrane-bound proteinase complex also known as 170 kDa Melanoma Membrane Gelatinase, Integral Membrane Serine Proteinase and Seprase. Some cells make only FAPa homodimers, some only DPP4 homodimers. The monomer is inactive. FAP, alpha is selectively expressed in reactive stromal fibroblasts of epithelial cancers, granulation tissue of healing wounds, and malignant cells of bone and soft tissue sarcomas. This protein is thought to be involved in the control of fibroblast growth or epithelial-mesenchymal interactions during development, tissue repair, and epithelial carcinogenesis.
