Truncated and inactivated form of SCRA, a protein involved in male-mediated self-incompatibility when active. Most A.thaliana cultivars contain such an inactive form and thus, are self-fertiles. By contrast to A.lyrata and A.halleri, self-incompatible species with full-length SCRA isoforms, A.thaliana is self-compatible with impaired SCRA protein. Belongs to the DEFL family.
