Survivin

Tropomyosin receptor kinase B (TrkB) is a member of the Trk receptor tyrosine kinases family consisting of TrkA, TrkB and TrkC. The sequence of these family members is highly conserved.

Caspase 7 (also known as CASP7, Mch3, ICE-LAP3, CMH-1) is a member of caspase family of cysteine proteases. It is an apoptosis-related cystein peptidase encoded by the CASP7 gene in humans. CASP7 homologous sequences have been identified in nearly all mammals. Similar to Caspase 3, Caspase-7 is an effector caspase and plays a key role in apoptotic execution.

Proliferating Cell Nuclear Antigen (PCNA), also known as the polymerase delta auxiliary protein, is a nuclear protein essential for DNA replication as well as DNA excision and mismatch repair pathways. It has a large role in cell cycle regulation and response of cells to stress.

Tropomyosin receptor kinase B (TrkB) is a member of the Trk receptor tyrosine kinases family consisting of TrkA, TrkB and TrkC. The sequence of these family members is highly conserved. TrK's are activated by several neurotrophins, which are small protein growth factors that play a role in survival and differentiation of distinct cell populations.

The Survivin antibody is widely used in apoptosis studies, and as a cellular marker. Today, biochemists have a wide range of Survivin antibody products to choose from, suitable for use in Western Blot, Chromatin Immunoprecipitation (ChIP), Immunofluorescence and similar assays.

Survivin (BRIC5) is an inhibitor of apoptosis that also promotes cellular adaptation under stressful conditions and helps to regulate cell division. Recently, an antibody study by Dr. H Wang et al. at Brown University [PMID: 20826784] found that Survivin is acetylated at lysine residue 129, thereby affecting its subsequent subcellular localization.
