Kalirin
Protein-coding gene in the species Homo sapiens / From Wikipedia, the free encyclopedia
Kalirin, also known as Huntingtin-associated protein-interacting protein (HAPIP), protein duo (DUO), or serine/threonine-protein kinase with Dbl- and pleckstrin homology domain, is a protein that in humans is encoded by the KALRN gene.[5][6] Kalirin was first identified in 1997 as a protein interacting with huntingtin-associated protein 1.[5] Is also known to play an important role in nerve growth and axonal development.[7]
Kalirin is a member of the Dbl family of proteins and is a Rho guanine nucleotide exchange factor.
It is named after the multiple-handed Hindu goddess Kali for its ability to interact with numerous other proteins. Kalirin's other name, DUO, comes from the fact that it is 98% identical to rat DUO protein and 80.6% identical to a human protein named TRIO. Unlike TRIO, which is expressed in numerous tissues, Kalirin isoforms are mainly found in the brain.
