CASK Antibody [PT55]

CASK Antibody [PT55] is a rabbit recombinant monoclonal antibody directed against CASK, offered by Assay Genie for research applications. Reported applications include WB, IHC and ICC/IF. Reported reactivity: Human, Mouse and Rat. Supplied as IgG Kappa, purified by AmMag™ Ultra AT Protein A MagBeads.

CASK (calcium/calmodulin-dependent serine protein kinase) is a ~112 kDa member of the membrane-associated guanylate kinase (MAGUK) family, functioning as a critical scaffolding protein in neuronal development and synaptic organization. Structurally, CASK integrates multiple signaling domains—including a CaMK-like kinase domain, SH3 domain, PDZ domain, and a guanylate kinase (GUK) homology domain—enabling it to anchor transmembrane proteins to the cytoskeleton and intracellular signaling complexes. In the nervous system, CASK plays a pivotal role in stabilizing synaptic architecture by binding to neurexins at the presynaptic membrane, facilitating the assembly of pre- and postsynaptic structures. Beyond its cytoplasmic functions, a nuclear fraction of CASK translocates to the nucleus, where it acts as a transcriptional co-activator, influencing gene expression programs essential for neurodevelopment. Loss-of-function studies underscore CASK’s essential role: mice with CASK gene disruptions exhibit perinatal lethality, highlighting its necessity for survival. Additionally, CASK is expressed in non-neuronal tissues, including basal keratinocytes and developing hair follicles, suggesting broader roles in tissue development and wound repair. Emerging evidence links CASK dysfunction to neurodevelopmental and neurodegenerative disorders, including intellectual disability, microcephaly, and cerebellar atrophy. As a multifunctional regulator of synaptic integrity and gene expression, CASK is increasingly recognized as a key molecular target in neuroscience and neurodegeneration research. This antibody is also available conjugated to ATTO 390, ATTO 488, ATTO 594, APC, Biotin, FITC, HRP, PerCP and RPE. Supplied in 100 µg.
