Kptn Gene Summary [Mouse]

Predicted to enable actin filament binding activity. Predicted to be involved in several processes, including cellular response to amino acid starvation; cellular response to glucose starvation; and negative regulation of TORC1 signaling. Predicted to be located in postsynaptic actin cytoskeleton and stereocilium. Predicted to be part of KICSTOR complex and filamentous actin. Predicted to be active in lamellipodium. Used to study autosomal recessive intellectual developmental disorder 41. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder 41. Orthologous to human KPTN (kaptin, actin binding protein). [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 Kptn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

  • protein binding
  • FG-GAP-like repeat
