See sections below for more information
The gene glial cells missing is referred to in FlyBase by the symbol Dmel\gcm (CG12245, FBgn0014179). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: DNA binding. There is experimental evidence for 16 unique biological process terms, many of which group under: biological regulation; glial cell differentiation; system development; regulation of developmental process; neuron differentiation; immune system process; regulation of neurogenesis; cell proliferation; cellular component organization or biogenesis; establishment of blood-brain barrier; cell fate commitment; hemopoietic or lymphoid organ development. 54 alleles are reported. The phenotypes of these alleles are annotated with: organ system; organ system subdivision; multicellular structure; non-connected developing system; larval abdominal segment; embryonic/larval neuron; peripheral nervous system; portion of tissue; embryonic/larval hemocoel; adult segment. It has one annotated transcript and one annotated polypeptide. Protein features are: Transcription regulator, GCM-like. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of extremely low expression. Peak expression observed within 00-18 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: larval central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1631126_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of gcm. Gene sequence location is 2L:9579449..9581742.

Additional Descriptive Data
gcm transcripts are expressed in glial precursors and immature glial cells during a short period of gliogenesis. Expression is first detected in early stage 11 in the longitudinal glioblast. By mid stage 11, 2-3 other cells per hemisegment express gcm. Two of these have been identified as NB6-4 and the medial-most cell body glial cell (VUM support cell). By early stage 12, expression is detected in several other cells which are also developing glial cells. Expression fades during stage 12 and is hardly detectable in stage 13. Enhancer trap expression was used to trace the gcm-expressing cells to later developmental stages. It was found that gcm is expressed in all glial precursors and immature glial cells except those derived from the mesectoderm. Outside of the CNS, gcm is expressed in the most anterior region of the presumptive mesoderm beginning at the cellular blastoderm stage, in the brain neurogenic region, and in the PNS neurogenic region.
gcm transcripts are first detected by in situ hybridization in the head region of the embryo at the end of the blastoderm stage. At stage 10, expression is still very prominent in the procephalic mesoderm. Additionally staining is seem in one cell per hemisegment in the lateral ectoderm which may correspond to PNS. A second, more medially located cell, may be the longitudinal glioblast. By stage 11, expression decreases in the hemocyte lineage and becomes more prominent in glial cells of the PNS and CNS. The staining pattern appears d fferent in the thoracic and abdominal segments reflecting the different organization of the glial cells. No signal is observed in cells migrating from the procephalic mesoderm after stage 11.
gcm transcripts are initially expressed in an anterior ventral patch in the cellular blastoderm embryo. During gastrulation, these cells invaginate at the end of the ventral furrow just anterior to the cephalic furrow in an area that gives rise to the cephalic mesoderm. Cephalic expression fades after stage 10. During stages 11-12, in each hemisegment, two patches of 3-5 ectodermal cells sequentially and transiently express gcm. From each patch, a single large blast cell delaminates and maintains gcm expression. These are tentatively identified as the peripheral glioblast and the longitudinal glioblast. By late stage 11, all of the progeny of these glioblasts as well as additional glial cells express gcm. Glial expression is gone by stage 15. In the brain lobes, gcm is expressed in a complex pattern through stage 17. In the PNS, gcm is transiently expressed in all repo-positive glia along peripheral axon pathways and associated with sensory organs.

hkb triggers gcm autoregulation via direct physical interaction.
gcm and gcm2 cooperate with the hh pathway to regualte neurogenesis in the lamina.
Lack of both gcm and gcm2 eliminates all lateral glial cells.
N signalling positively regulates gcm expression in the context of subperineurial glial cell development.
gcm is required for the formation of subperineurial glial cells.
The decision to express gcm in the sensory organ lineage is dependent upon cell-cell communication.
mira and pros seem to be upstream of gcm in the cascade of cell fate decision in the NB6-4T lineage.
Restricted expression of gcm is required for the developmental program of embryonic plasmatocytes.
gcm is necessary to induce glial differentiation in the peripheral nervous system.
Gliogenesis depends on gcm through asymmetric division of neuroglioblasts.
gcm can induce gliogenesis in mesodermal cells, indicating that gliogenesis does not require a ground neural state.
gcm is required in the hemocyte/macrophage cell lineage.
On the basis of structural as well as functional criteria gcm is a transcription factor with novel DNA binding domain that recognises the motif AT(G/A)CGGGT.
gcm encodes a novel DNA binding protein, which has its DNA binding activity localised within the N-terminal 181 amino acids. The protein binds with high specificity to the sequence, (A/G)CCCGCAT. Eleven such gcm binding sequences are found in the upstream region of the repo gene.
gcm is necessary for glial cell fate commitment. Mutations prevent glial cell determination in the embryonic central and peripheral nervous system. Absence of glial cells is the consequence of a cell fate switch from glia to neurones.
Mutations at gcm have severely disrupted longitudinal connectives. gcm was identified during an enhancer detector screen, imprecise excisions of the P-element generated severe alleles in which the longitudunal connectives have few axons in most segments. Expression patterns of mutant alleles indicate that the gcm mutation disrupts early steps of glial development. gcm may be an upstream element in the cascade that controls the repo expression.
Phenotypic analysis reveals that glial/neuron determination is governed by a single molecule, gcm. All CNS cells are originally bipotential so that they can differentiate into both neurons and glial cells with neuronal differentiation as a default. They differentiate into neurons when gcm is absent while they differentiate into glial cells when gcm is present.
Cloning, molecularly characterisation and genetic analysis of gcm.
gcm is involved in the migratory, not rotatory, aspect of lateral chordotonal (Lch) neuron development.
