Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

| Precautions | FKBP12 Antibody is for research use only and not for use in diagnostic or therapeutic procedures. |
| Name | FKBP1A |
|---|---|
| Synonyms | FKBP1, FKBP12 |
| Function | Keeps in an inactive conformation TGFBR1, the TGF-beta type I serine/threonine kinase receptor, preventing TGF-beta receptor activation in absence of ligand. Recruits SMAD7 to ACVR1B which prevents the association of SMAD2 and SMAD3 with the activin receptor complex, thereby blocking the activin signal. May modulate the RYR1 calcium channel activity. PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. |

Background
FKBP, or FK506 binding protein, is a family of proteins that have prolyl isomerase activity and are related to the cyclophilins in function (1). FKBP12, also called FKBP1, was originally identified as a target of FK506 and rapamycin activity and catalyzes the transition between cis and transproline residues critical for proper folding of proteins (2). FKBP12 is an abundant, evolutionarily conserved cytoplasmic protein that is an important regulator of diverse array of cellular processes including T cell activation, entry into the cell cycle and intracellular calcium release (3-5).
