Disks large homolog 1 (DLG1)

Essential multidomain scaffolding protein required for normal development (By similarity). Recruits channels, receptors and signaling molecules into discrete plasma membrane domains in polarized cells.

May play a role in adherens junction assembly, signal transduction, cell proliferation, synaptogenesis and lymphocyte activation. Regulates the excitability of cardiac myocytes by regulating the functional expression of Kv4 channels.
