Abstract

The charge heterogeneity of class III beta-tubulin (beta III) during neural development was analyzed by high-resolution isoelectric focusing/two-dimensional polyacrylamide gel electrophoresis in combination with site-specific proteolytic digestion and immunological detection. The number of beta III isoforms (charge variants) gradually increases from one in embryonic brain to seven in adult brain. All of the charge heterogeneity is due to posttranslationally modified sites located within the extreme C-terminal region of the beta III polypeptide. One beta III isoform is present in testis, the only other tissue in which this isotype is expressed. The testis beta III isoform cofocuses with the earliest-appearing embryonic brain beta III charge variant. Our results indicate that the posttranslational modifications of beta III are developmentally regulated, occur at more than one site, and are neuron-specific. The location of these modifications within the extreme C-terminal domain suggests that their function is to modulate the interaction of tubulin with microtubule-associated proteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
