LIM domains are proposed to function in protein–protein recognition in a variety of contexts including gene transcription and development and in cytoskeletal interaction.
The gene product is involved in the assembly of an actin filament-associated complex essential for transmission of ret/ptc2 mitogenic signaling.
The biological function is likely to be that of an adapter, with the PDZ domain localizing the LIM-binding proteins to actin filaments of both skeletal muscle and nonmuscle tissues.
Alternative splicing of this gene results in multiple transcript variants.
