Ready-to-use ELISA kits are available for the detection of DUF 10, an alias of the protein, kalirin RhoGEF kinase. The official gene symbol is KALRN. The protein, with a mass of 340.3 kDa and length of 2986 residues, is reported to be cytoplasmic. It is a member of the Protein kinase superfamily, CAMK Ser/Thr protein kinase family and may be known by other names, including: DUO, DUET, ARHGEF24, serine/threonine-protein kinase with Dbl- and pleckstrin homology domain, huntingtin-associated protein interacting protein (duo), and kalirin.
