CASP1 — Asparagus officinalis

Summary

A4U43_C02F7940, designated CASP1 in asparagus (Asparagus officinalis) on chromosome 2, encodes a protein belonging to the CASP/CASPL family, characterized by a CASP domain. The product is associated with protein homodimerization and protein binding activities. It has been linked to cell-cell junction assembly, cell wall modification and organization, proteolysis, regulation of protein stability, and memory-related processes. The protein localizes to the Casparian strip and the plasmalemma. Associations with skin development have also been noted. Studies of related CASP family members in other species connect this gene family to Casparian strip formation, chlorophyll content, and callus induction, though these functions are not yet established in asparagus itself.
