Doublecortin-like kinase protein 1 (DCLK1) [5] [6] [7] [8] is an enzyme that in humans is encoded by the DCLK1 gene. [5] [6] [8] Its C-terminal domain in rats is expressed independently from an alternative transcript, cpg16, and can function alone as a serine/threonine protein kinase that is cyclic AMP dependent. [9] [10]
DCLK1 expression is a marker for tuft cells, a type of chemosensory cell of the intestinal epithelium. [7] [11]
