CDAN1 (Codanin-1) is a protein encoded by the *CDAN1* gene in humans, primarily associated with congenital dyserythropoietic anemia type I (CDA-I), a rare inherited blood disorder characterized by ineffective red blood cell production. This protein plays a critical role in chromatin assembly during DNA replication and repair, particularly during erythroid (red blood cell) development. Structurally, CDAN1 contains conserved domains such as the N-terminal histone chaperone-like region and a C-terminal RID (Ribonuclease inhibitor-like domain) that may interact with histones or chromatin-modifying enzymes.
Mutations in *CDAN1* disrupt normal erythropoiesis, leading to morphological abnormalities in erythroblasts, including chromatin bridging and nuclear irregularities. These defects highlight CDAN1’s importance in maintaining nuclear integrity and chromatin organization during cell division. Recombinant CDAN1 protein, produced via genetic engineering in systems like bacterial or mammalian cells, enables functional studies to dissect its molecular mechanisms. Researchers utilize it to investigate interactions with histones, chromatin remodelers, or other partners implicated in CDA-I pathogenesis.
Beyond basic research, recombinant CDAN1 holds potential for developing therapeutic strategies, such as gene therapy or drug screening platforms targeting CDA-I. Its study also contributes to broader insights into chromatin dynamics and disorders linked to genomic instability.
