| Type | Antibody | against CeMyoD, a homologue of a transcription factor | |
| In_situ | |||
| Reporter_gene | |||
| Pattern | Antibody staining: Transient nuclear staining in early MS lineage identical to lacZ pattern. Stable nuclear expression begins in the 2 daughters of D at the ~90 cell stage, then C and MS lineages that give rise to body wall muscle cells (bwm). The lone AB bwm appears positive after born. At pretzel stage, nuclear staining in the 6 GLR cells. Staining persists throughout postembryonic development in bwm cells, including post-embryonically born bwm. | ||
| lacZ reporter gene expression: Multiple constructs with multiple lines. Transient expression in 2 MS daughters and the 4 MS granddaughters. Stable expression begins at ~90 cell stage in two daughters of D. Then on in C, MS lineages that give rise to body wall muscle precursors. At pretzel stage, hlh-1 is also expressed in the 6 GLR cells. | |||
| positive hybridisation to RNA (in _situ) same as lacZ pattern except RNA appears to go away at bean stage and reappear later in embryogenesis | |||
| Remark | 90 cell embryo(author) = 88-cell embryo(curator). | ||
| CeMyoD :Basic Helix-loop-helix transcription factor. Related to the vertebrate MyoD family that is involved in the regulation of striated muscle cell fate.Vertebrate Homologs: Mammalian factors MyoD, MRF-4, Myf-5, myogenin.Invertebrate Homologs: Drosophila protein "Nautilus", sea urchin "SUM-1". Legacy Data: Author "Seydoux GC" "Krause MW". Date 1995-08. | |||
| Function: Putative null mutation (cc450) of L. Chen and A.Fire suggests important role for CeMyoD in body wall muscle cell function and morphogenesis. CeMyoD is not required for bwm cell fate determination but is for proper bwm cell differentiation | |||
