NCLN (Nicalin): NCLN is a component of the nicalin-NOMO (nodal modulator) complex, which plays a role in key cellular processes, including signalling pathways that regulate embryonic development and organ formation. Although its precise functions are still under investigation, NCLN is thought to help modulate pathways such as Nodal signalling, which is crucial for developmental patterning. Its role within this complex indicates potential involvement in developmental disorders and diseases linked to dysregulated signalling pathways.
