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