Gene Snapshot

big brain (bib) encodes a non-selective cation channel in the aquaporin family. Its function is required for optimal Notch signaling to restrain neurogenesis. [Date last reviewed: 2018-09-06]

Gene Group (FlyBase)

AQUAPORINS -: Aquaporins (AQPs) are integral membrane proteins with a central pore formed form two highly conserved hydrophobic regions, NPA boxes, which contain the signature Asp-Pro-Ala motif. They selectively allow the transfer of water across the membranes. (Adapted from PMID:22542572).

Protein Function (UniProtKB)

Essential for proper differentiation of ectoderm. Acts synergistically with neurogenic locus proteins Notch and Delta during the separation of neural and epidermal cell lineages in response to the lateral inhibition signal. Voltage-insensitive monovalent cation channel. Ion transport is blocked by the presence of divalent cations.

(UniProt, P23645)

Phenotypic Description (Red Book; Lindsley and Zimm 1992)

bib: big brain

Recessive embryonic lethal, a neurogenic mutant. Homozygotes fail to form ventral, lateral, and most of the cephalic epidermis. Central nervous system hypertrophied by recruitment of presumptive epidermal cells, but exhibiting considerable architectural normality. Most epidermal sense organs can be recognized in electron microscope preparations; chordotonal organs prevalent but with abnormal structures, perhaps owing to disrupted attachment. Supernumerary peripheral elements formed by recruitment of presumptive epidermal cells [Hartenstein and Campos-Ortega, 1986, Wilhelm Roux's Arch. Dev. Biol. 195: 210-21 (fig.). Cuticular clones of cells homozygous for bib1 or bib6 exhibit normal development (Dietrich and Campos-Ortega, 1984, J. Neurogenet. 1: 315-32). Effects on central nervous system intermediate with respect to mutations at other neurogenic loci. Insensitive to changes in dosage of other neurogenic genes (de la Concha, Dietrich, Weigel, and Campos-Ortega, 1988, Genetics 118: 499-508).

Expression Summary Ribbons

Colored tiles in ribbon indicate that the Fly Cell Atlas project found the gene expressed in that cell type. Darker colors mean that more cells of that cell type express the gene:

low

high

Colorless tiles indicate that there is no scRNAseq data for the gene in that cell type.

Colored tiles in ribbon indicate that expression data (RNA and/or protein) has been curated by FlyBase for that anatomical location. Colorless tiles indicate that there is no curated data for that location.

Colored tiles in the ribbon indicate the average RNA expression level of the gene at the indicated stages:

low

high

Additional Descriptive Data

bib transcript is detected in all somatic cells at the start of cellularization. By the completion of cellularization, bib is absent from a 17-cell-wide ventral strip which includes the presumptive mesoderm cells and two rows of ectodermal cells. Through stage 8, bib expression is maintained in most ectodermal tissue. During neuroblast delamination at late stage 8-stage 9, neuroblasts which segregate from the ectodermal layer lose bib expression. At the end of germ-band extension, the mesoderm begins to express bib. By late stage 11, bib expression disappears first from the epidermis, then the mesoderm. After stage 12, bib is barely detectable in the embryo.

Dvir\bib is cloned, sequenced and compared to bib : the channel domain and both cytoplasmic domains are highly conserved.

(Burris et al., 1998)

bib function is required autonomously in epidermal precursors to prevent neural development.

(Doherty et al., 1997)

Alleles of bib and neur show no interaction with da in ovary development.

(Cummings and Cronmiller, 1994)

bib is a neurogenic gene required initially to ensure the correct number of PNS precursors. bib is not required for the late epidermal maintenance function.

(Bodmer et al., 1993)

The embryonic phenotype of neurogenic mutations was examined in most tissues using Ecol\lacZ enhancer trap lines. All alleles examined show defects in many organs from all three germ layers. At least for ectodermally and endodermally derived tissues, neurogenic gene function is primarily involved in interactions among cells that need to acquire or maintain an epithelial phenotype.

(Hartenstein et al., 1992)

Recessive embryonic lethal, a neurogenic mutant. Homozygotes fail to form ventral, lateral and most of the cephalic epidermis. Central nervous system hypertrophied by recruitment of presumptive epidermal cells, but exhibiting considerable architectural normality. Most epidermal sense organs can be recognized in electron microscope preparations; chordotonal organs prevalent but with abnormal structures, perhaps owing to disrupted attachment.

(Lindsley and Zimm, 1992)

Loss of bib function approximately doubles the number of neuronal precursors and their progeny cells in the embryonic peripheral nervous system. Mosaic studies reveal a hypertrophy of sensory bristles in bib mutant patches in adult flies, in contrast to results of Dietrich and Campos-Ortega, 1984.

(Rao et al., 1992)

Mutant alleles cause hypertrophy in nau expressing cells, a 2-5 fold increase in nau expressing cells per cluster relative to wild type. The clusters enlarge so much that they merge to form superclusters across the midline.

(Corbin et al., 1991)

bib is needed for proper mesoderm differentiation prior to the onset of nau expression.

(Corbin et al., 1991)

Ecol\lacZ reporter gene constructs demonstrate that neurogenic loci are required to restrict the number of competent cells that will become sensory mother cells, SMCs.

(Goriely et al., 1991)

Mutations of mam, bib and neur in an heterozygous condition had no effect on the expression of N^Ax-59d or N^Ax-59b except when coupled in cis with N^fa-g. The neurogenic mutations suppress the wing venation phenotype of N.

(Portin and Rantanen, 1991)

Characterisation of bib genomic and complementary DNA suggests the bib product may mediate intercellular communication in a pathway separate from the one involving the products of other neurogenic genes.

(Rao et al., 1990)

bib mutants show no interaction with dx.

(Xu and Artavanis-Tsakonas, 1990)

Neural hyperplasia, caused by mutations in bib, can be prevented by the presence of another neurogenic mutation.

(Brand and Campos-Ortega, 1988)

Effects on central nervous system intermediate with respect to mutations at other neurogenic loci. Insensitive to changes in dosage of other neurogenic genes.

(de la Concha et al., 1988)

Supernumerary peripheral elements formed by recruitment of presumptive epidermal cells.
