This gene encodes a protein with a gelsolin-like actin binding domain and an N-terminal leucine-rich repeat-protein protein interaction domain. The protein is similar to a Drosophila protein involved in early embryogenesis and the structural organization of indirect flight muscle. The gene is located within the Smith-Magenis syndrome region on chromosome 17. Mutations in this gene leads to abnormal muscle function, arrested development and embryonic lethality. The protein sequence shows that this might be a regulator of cytoskeleton and may have a role during cell division.
