The DCD domain is found in plant proteins involved in development and cell death. The DCD domain is an approximately 130 amino acid long stretch that contains several mostly invariable motifs. These include a FGLP and a LFL motif at the N-terminus and a PAQV and a PLxE motif towards the C-terminus of the domain. The DCD domain is present in proteins with different architectures. Some of these proteins contain additional recognisable motifs, like the KELCH repeats or the ParB domain.
