ab94275 is a 293T cell transfected lysate in which Human CSEN has been transiently over-expressed using a pCMV-CSEN plasmid. The lysate is provided in 1X Sample Buffer. Note: For more detailed how the transfected lysate was prepared view preparation notes
Function: Calcium-dependent transcriptional repressor that binds to the DRE element of genes including PDYN and FOS. Affinity for DNA is reduced upon binding to calcium and enhanced by binding to magnesium. Seems to be involved in nociception.
Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels, such as KCND2/Kv4.2 and KCND3/Kv4.3. Modulates channel expression at the cell membrane, gating characteristics, inactivation kinetics and rate of recovery from inactivation in a calcium-dependent and isoform-specific manner.
May play a role in the regulation of PSEN2 proteolytic processing and apoptosis. Together with PSEN2 involved in modulation of beta-amyloid formation.
PTM: Palmitoylated. Palmitoylation enhances association with the plasma membrane.
Proteolytically cleaved by caspase-3.
Phosphorylation at Ser-63 inhibits cleavage by CASP3.
Similarity: Belongs to the recoverin family.
Contains 4 EF-hand domains.
Tissue specificity: Highly expressed in brain. Widely expressed at lower levels. Expression levels are elevated in brain cortex regions affected by Alzheimer disease.
