Iqsec1 Gene Summary [Mouse]
Enables protein kinase binding activity. Involved in several processes, including positive regulation of focal adhesion disassembly; positive regulation of keratinocyte migration; and regulation of postsynaptic neurotransmitter receptor internalization. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and postsynaptic density, intracellular component. Is expressed in central nervous system; forelimb muscle; sensory organ; and viscerocranium. Human ortholog(s) of this gene implicated in intellectual developmental disorder with short stature and behavioral abnormalities and lung adenocarcinoma. Orthologous to human IQSEC1 (IQ motif and Sec7 domain ArfGEF 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Iqsec1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
