Gene Summary
fandango (fand) encodes a subunit of the NTC/Prp19 complex, which is essential for efficient spliceosome activation. It regulates the efficiency of splicing of zygotic transcripts and their abundance. It is required for normal cellularization, tracheal cell migration, and epidermal morphogenesis in the embryo.

Gene Group (FlyBase)
SPLICEOSOME COMPLEX B -
Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. After the assembly of complex A on pre-mRNA, the U4-U6 and U5 snRNPs are recruited as a preassembled tri-snRNP to form complex B. U5 snRNP binds exons at the 5' site. (Adapted from PMID:24452469 and PMID:23118483).
SPLICEOSOME COMPLEX C -
Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. Complex B undergoes a number of structural rearrangements and U4 and U1 snRNPs dissociate to generate complex C, the catalytic spliceosome. (Adapted from PMID:24452469 and PMID:23118483).
SPLICEOSOME COMPLEX P -
Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. Complex P, the post-spliceosomal complex, is formed after the catalytic removal of the intron by complex C. Complex P contains the lariat intron and spliced exons. (Adapted from PMID:24452469 and PMID:23118483).
Protein Function (UniProtKB)
Subunit of the NTC(Nineteen)/Prp19 complex, which is part of the spliceosome (PubMed:24755291, PubMed:28087625). The complex participates in spliceosome assembly, its remodeling and is required for efficient spliceosome activation (PubMed:24755291, PubMed:28087625). Essential for efficient pre-mRNA splicing (PubMed:24755291, PubMed:28087625). In embryos, efficient pre-mRNA splicing of zygotic transcripts is essential during dynamic cellular processes that require rapid division and/or dramatic changes in gene expression such as blastoderm cellularization, tracheal branching morphogenesis, Malpighian morphogenesis and epidermal development (PubMed:10502111, PubMed:24755291, PubMed:28087625). Part of its role in promoting embryo tracheal development is also due to specifically splicing bnl transcripts which results in the activation of the BNL-FGF pathway (PubMed:28087625).

        Splicing of early zygotic, but not maternally encoded pre-mRNAs is affected in mutant embryos.

        S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.

        fand is essential for nerve cell migration and the establishment of axonal pathways in the developing nervous system.

        Additional comments

        The 'faint sausage (fas)' phenotype, previously associated the immunoglobulin domain protein CG17716 (Lekven et al, 1998; FBrf0103312), is now shown to be caused by mutations in CG6197, also known as 'fand' (Guilgur et al, 2014; FBrf0224810).

        Not allelic to shot.

        Nomenclature History
        Source for database identify of

        Source for identity of: fand CG6197

        Nomenclature comments

        FlyBase curator comment: Based on their findings, Sauerwald et al, 2017 (FBrf0234822) refer to the CG6197/fand gene as 'fas'. However, given the history, it would likely be confusing to effectively transfer the 'fas/faint sausage' nomenclature from the CG17716 gene to the fand/CG6197 gene in FlyBase. Thus, FlyBase has: (i) retained 'fand/fandango' as the FlyBase symbol/name of CG6197 (based on FBrf0224810), but added 'fas/faint sausage' as synonyms (based on FBrf0234822); and (ii) reverted the current 'fas/faint sausage' gene to just have 'CG17716' as its FlyBase symbol (at least until it is given a more appropriate symbol/name), while retaining 'fas/faint sausage' as synonyms.

        Etymology

        The gene is named "fandango", after the Iberian folk dance, based on the phenotype of mutant embryos.
