Is predicted to encode a protein with the following domains: CAP superfamily; Actin-crosslinking; Cysteine-rich secretory protein family; CAP domain; and Cysteine-rich secretory protein-related. Is an ortholog of C. elegans F09B9.5 and lon-1. In C. elegans, lon-1 is involved in several processes, including negative regulation of BMP signaling pathway; negative regulation of DNA endoreduplication; and positive regulation of growth rate.
