Conserved Site

Cornichon, conserved site (IPR033466)

Short name: Cornichon_conserved


The drosophila cornichon protein (gene: cni), the founding member of this family, is an integral component of the COPII-coated vesicles that mediate cargo export from the yeast endoplasmic reticulum (ER) [PMID: 16396907]. It is required in the germline for dorsal-ventral signalling. The dorsal-ventral pattern formation involves a reorganisation of the microtubule network correlated with the movement of the oocyte nucleus, and depending on the initial correct establishment of the anterior-posterior axis via a signal from the oocyte produced by cornichon and gurken and received by torpedo protein in the follicle cells [PMID: 7540118].

This entry represents a conserved region located in the loop between the first and second transmembrane regions. This conserved region contains three acidic residues.
