CDK5 Activator 1 Antibody (739304)

Western blot shows lysates of human brain (cortex) tissue and human brain (hippocampus) tissue. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human CDK5 Activator 1 Monoclonal Antibody (Catalog # MAB7357) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for CDK5 Activator 1 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

Cyclin dependent kinase 5 regulatory subunit 1 (CDK5R1) is a 35 kDa protein that associates with and activates CDK5. Its expression is restricted to neurons and is required for normal brain development. CDK5R1 can be cleaved by calpain at Phe98-Ala99 which liberates a C-terminal fragment known as p25. p25 induces prolonged activation of CDK5 and broadens the substrate specificity of CDK5 to include tau which is aberrantly phosphorylated in Alzheimer's disease. Full length CDK5R1 is myristoylated at Gly2 and is preferentially localized to membranes at the cell periphery. p25 lacks this modification and is enriched in the nucleus and perinuclear regions. p25 accumulates in the brains of Alzheimer's patients where it promotes neuronal apoptosis and cytoskeletal abnormalities. Within aa 100-307, human CDK5R1 shares 99% aa sequence identity with mouse and rat CDK5R1.
