Kinetics of the regeneration of sea-urchin cilia. II. Regeneration of animalized cilia.
The kinetics of the regeneration of cilia of Arbacia punctulata animalized by treatment with trypsin have been examined. The cilia regenerate with biphasic kinetics: an initial linear phase which changes abruptly to a second, slower linear rate. Inhibition of protein synthesis with 10 microM emetine has little effect on the first phase but totally abolishes the second, suggesting that the first...
متن کاملKinetics of the regeneration of sea-urchin cilia.
The kinetics of the regeneration of cilia of the sea urchin Tripneutes gratilla have been examined. The maximum cilia length is attained asymptotically which may reflect the transport of precursors to the distal tip. However, a detailed analysis indicates that the maximum length is regulated by a mechanism other than the availability of precursors at the distal end. It is argued that this contr...
متن کاملGlycosyltrasferase activity in developing sea-urchin embryos.
The developmental course of activity changes of 4 endogenous membrane glycosyltransferases: UDP-glucose : glycosyltrasferase, UDP-galactose : glycosyltransferase, GDP-mannose: glycosyltransferase, and UD-PN-acetylglucosamine : glycosyltransferase was determined in various stages of developing sea-urchin embryos from unfertilized eggs up to the 16-cell stage. The results show that there is a 2-f...
متن کاملTubulin in sea urchin embryonic cilia: post-translational modifications during regeneration.
Tubulin is the major protein found in the membrane/periaxonemal matrix fraction of mature sea urchin embryonic cilia but its distribution and possible function during ciliary assembly are unknown. Hypertonic salt may be used to deciliate the embryos, allowing synchronous regrowth of cilia and subsequent deciliation of the regenerating embryos at various times. During the earliest stages of rege...
متن کاملTubulin and tektin in sea urchin embryonic cilia: pathways of protein incorporation during turnover and regeneration.
Axonemal precursor tubulin is the major protein component of the detergent-soluble membrane/matrix fraction of sea urchin embryonic cilia. Its unusual abundance may reflect the rapid turnover of these cilia, a process that is further documented here. However, whether during induced regeneration or normal turnover and growth, most other newly synthesized axonemal proteins are not detectable in t...
