microtubule end-binding protein - controls the plus end of growing microtubules - targets other microtubule-associated proteins to the plus end and thereby regulates interactions of microtubules with the cell cortex, mitotic kinetochores, and different cellular organelles

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
Low-frequency RNA-Seq exon junction(s) not annotated.

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
In wild-type egg chambers, Eb1 foci are detected throughout the oocyte, with enrichment at the posterior pole.
Numerous Eb1 foci are detectable throughout the nurse cell and oocyte cytoplasm of stage 5-8 egg chambers. By stage 9, a distinct accumulation of Eb1 foci are found at the posterior of the oocyte. This polar distribution of Eb1 is maintained into late stages of oogenesis (S10 onward). A three dimensional projection through the center of the oocyte shows Eb1 enriched at the posterior of stage 10 oocytes, in a layer closer to the center of the egg chamber than the pole plasm marker vas. Additional foci were also present at the oocyte cortex and at lower levels within the oocyte cytoplasm.

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.
polyclonal
New stable cell line derived from S2-Mt-EB1-GFP : S2 cells stably transformed to express GFP-tagged Eb1 from a metallothionein promoter.
S2 cells treated with RNAi against chb do not show a significant change in poleward flux rates of tubulin subunits in mitotic spindles compared to control cells, but do show suppressed α-tubulin turnover at the microtubule plus ends of the spindles.
RNAi screen using dsRNA made from templates generated with primers directed against this gene results in aberrantly short spindles when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.
S2 cells transfected with dsRNA made from templates generated with primers directed against this gene show shortening of the metaphase spindle. Sometimes RNAi of this gene causes centrosome detachment from the kinetochore microtubules.
