Specifically, mD2LIC is required in the ventral node for the formation of monocilia, which are critical for generating the proper left–right axis. Loss of mD2LIC leads to altered node cell morphology and diminished or absent expression of key developmental regulators such as Foxa2, Shh, and subsequently Nodal in later developmental stages. Moreover, mD2LIC supports the survival of the anterior definitive endoderm and aids in maintaining the anterior neural ridge, likely by sustaining Foxa2/Hnf3β expression. Thus, the study identifies mD2LIC as a pivotal cytoplasmic dynein component that indirectly influences organiser and midline signalling required to establish ventral cell fates during embryogenesis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "While the request was to summarize the function of GPR50‑AS1, it is important to note that the provided abstract (PMID 15371312) does not mention GPR50‑AS1.
