AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

2.1 (northern blot)
There is only one protein coding transcript and one polypeptide associated with this gene
361 (aa)
Likely part of a multicomponent septin complex that includes pnut (PubMed:8590810). Interacts with pnut (PubMed:8590810). Interacts with park (PubMed:17456438).
Ubiquitinated by park, leading to its degradation by the proteasome.

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
Comment: maternally deposited
Septin1 transcripts are detected in embryos, larvae, pupae, and adults on northern blots.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
polyclonal
Shows particularly robust cycling of transcription in adult heads, as assessed by expression analysis using high density oligonucleotide arrays with probe generated during three 12-point time course experiments over the course of 6 days.
A complex of septin polypeptides is isolated that bind and hydrolyse GTP and form filaments. Their high degree of conservation, ubiquitous expression and proven role in cytokinesis suggests septins are certain to be important players in regulating cell architecture and function. Septins alone can form regular filamentous polymers, since filament formation is likely to be central to their localisation and function.
Sep1 localises to the leading edge of the cleavage furrows in dividing cells and in cellularising embryos. Sep1 is also concentrated in other locations that suggest additional roles unrelated to cytokinesis. Immunolocalisation and biochemical data suggest that Sep1 and pnut probably function as parts of a complex.
Defined as a transcription unit discovered by Northern blots, in vicinity of slgA gene.
