Serpin 42Da (Spn42Da) encodes an endopeptidase inhibitor involved in hormone processing regulation. [Date last reviewed: 2019-07-11]

Gene Group (FlyBase)

INHIBITORY SERPINS -: The serpin family is a structurally-related group of secreted proteins containing the serpin-fold, a 350-400 amino acid domain. Serpins (SERine Protease INhibitors) were first identified as a set of proteins able to inhibit proteases, acting by forming a covalent complex is formed with the target proteinase targeting it for degradation. (Adapted from FBrf0213937 and FBrf0209216).

Model Confidence:

Very high (pLDDT > 90)
Confident (90 > pLDDT > 70)
Low (70 > pLDDT > 50)
Very low (pLDDT < 50)

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

Expression Data

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

as determined by RNA-seq (RPKM) using whole organism samples modENCODE, Brown et al., 2014. For complete stage-specific expression data, view the modENCODE Development RNA-Seq section under High-Throughput Expression below.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete

cDNA Clones (94)

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 GBrowse for alignment of the cDNAs and ESTs to the gene model.

Drosophila Genomics Resource Center cDNA clones

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.

Additional comments

'Spn4' and 'Serp2' reports merged because: 'dSerp2' was mentioned in a single reference (FBrf0107050) as being similar to vertebrate 'neuroserpin' and that it maps to 42D-E. A later reference from the same author (FBrf0146814) says that 'neuroserpin' corresponds to CG9453/Spn4, a gene that has been mapped experimentally to 42D.

(FlyBase, 1992-)

Other Comments

Overexpression of Spn4 either in the mesoderm or in peptidergic neurons results in animals which develop normally to the end of the first larval instar, but are unable to moult.

(Osterwalder et al., 2002)

Identification: Identified on the basis of sequence similarity to serpins.
