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).

RanGAP is widely detected in neuroblasts and other cells in the central brain and optic lobes in third istar larvae. It is found in both type I and type II neuroblasts. Expression becomes more restricted in the pupal brain. It is found in the cytoplasm and or in a nuclear-membrane-bound SUMOylated form.
Rcc1 protein localizes around the outside of the karyosome in the oocyte.
The protein is localized to the cytoplamic side of the nuclear membrane in both adult testis cells and larval salivary gland cells.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
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.
aub mutations act as genetic enhancers of Segregation Distorter. This effect is still seen when aub mutations are targeted (by homologous recombination) to the Dp(2;2)RanGAPSD chromosome, indicating that the effect of aub mutations is not specific to the target Rsp-bearing chromosome.
Area matching Drosophila gene RanGAP, Acc. No. AF143860.
The truncated RanGap product encoded by SD distorting chromosomes (RanGapSD) retains normal enzyme activity, but has abnormal subcellular location, being distributed diffusely throughout the cytoplasm and also having a distinct nuclear component in primary spermatocytes and salivary gland cells. Mislocalisation of the active RanGapSD product to the nucleus is responsible for segregation distortion (distortion is abolished if enzymatic activity or nuclear localisation of the RanGapSD product is perturbed).
A mutation of RanGap generated by loss of a P-element in RanGap exhibits a maternal effect embryonic lethal phenotype. Homozygous females are completely normal but hemizygotes are sterile regardless of the genotype of the male. Embryos from these females die before the syncytial blastoderm stage, around the 7th or 8th nuclear division. In addition, their nuclei are no longer mitotically synchronous and many appear abnormal in size and shape.
Encodes a Ran GTPase activator.
