Pseudokinases are proteins that structurally resemble kinases but lack the amino acid residues essential for catalytic phosphorylation activity, rendering them enzymatically inactive. They account for approximately 10% of the entire human kinome.
Their implication in a broad spectrum of diseases underscores their potential as therapeutic targets, paving the way for innovative treatment strategies that circumvent traditional reliance on enzymatic activity.
Carna's pseudokinases are available as biotinylated proteins for versatile applications across a wide range of research and development needs.
