CC -!- FUNCTION: Structural component of the gap junctions. Essential for
CC generation and/or maintenance of postembryonic neuroblasts and normal
CC development of optic lobe. {ECO:0000269|PubMed:1963867}.
CC -!- SUBUNIT: Heterooligomer of Inx2 and ogre.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000255|PROSITE-ProRule:PRU00351}. Cell junction, gap
CC junction. Basolateral cell membrane. Note=Accumulates in the
CC basolateral membrane of follicle cells in oocytes and epithelial cells
CC in embryonic salivary gland and hindgut.
CC -!- TISSUE SPECIFICITY: In ovary, expressed in follicle cells. Expressed
CC around the periphery of the embryo during cellular blastoderm
CC formation. Repeating epidermal pattern emerges from stage 11, high
CC levels of expression detected along the borders of each segment from
CC stage 13. At stage 13, expressed in the dorsal branch of the tracheal
CC system. During stage 15, detected in a few cells at each of the branch
CC points of the dorsal trunk and at low levels in cardioblasts. In
CC embryos, also expressed in the salivary gland and the hindgut (at
CC protein level). At stage 17, expressed in the dorsal side of the CNS.
CC Expressed in the imaginal wing disk. Expressed in larval CNS and in
CC tissues outside of the CNS. In pupae, expressed in the CNS and in
CC primary, secondary and tertiary pigment cells of the retina.
CC {ECO:0000269|PubMed:11960713, ECO:0000269|PubMed:15047872,
CC ECO:0000269|PubMed:19038051, ECO:0000269|PubMed:1963867}.
CC -!- DEVELOPMENTAL STAGE: Expressed during embryogenesis. Embryonic
CC expression commences during cellular blastoderm formation, increases
CC rapidly after cellularization and is maintained during the early stages
CC of gastrulation. Expressed in larvae and pupae.
CC {ECO:0000269|PubMed:11960713}.
CC -!- SIMILARITY: Belongs to the pannexin family. {ECO:0000255|PROSITE-
CC ProRule:PRU00351}.
