Signaling by juxtamembrane domain KIT mutants
Click the image above or here to open this pathway in the Pathway Browser
Mutations in the juxtamembrane region of KIT, encoded by exon 11, are especially prevalent as initiating events in gastrointestinal stromal tumors (GIST), but are also found at lower frequency in other cancers such as AML and melanoma (reviewed in Antonescu, 2006; Roskoski, 2018). Mutations in this region of KIT are believed to disrupt an auto-inhibitory function, leading to constitutive enzyme activation (Ma et al, 1999; Chan et al, 2003; Mol et al, 2004; reviewed in Roskoski, 2018). Unlike kinase domain mutants, juxtamembrane domain KIT mutants still undergo dimerization, although in a ligand-independent manner (Hirota et al, 1998; Furitsu et al, 1993; reviewed in Lennartsson and Roonstrand, 2012).
