NCLN (Nicalin): NCLN is a component of the nicalin-NOMO (nodal modulator) complex, which is involved in key cellular processes, including signaling pathways that regulate embryonic development and organ formation. While its precise functions are still being studied, NCLN is believed to help modulate pathways such as Nodal signaling, which is critical for developmental patterning. Its role within this complex suggests potential involvement in developmental disorders and diseases associated with dysregulated signaling pathways.
