A peripheral membrane protein with a relative molecular mass of 93,000 Da is associated with cytoplasmic domains of the inhibitory glycine receptor of mammalian spinal cord. Here, evidence is given that this 93-kDa protein binds to polymerized tubulin. First, tubulin cofractionated with the 93-kDa protein upon affinity purification of the glycine receptor.(More)
A specific binding assay was developed that monitors the interaction of 125I-labeled microtubule-associated proteins (MAPs) with tubulin or its fragments bound to nitrocellulose membrane. To identify the tubulin-binding domains for MAPs we have examined the binding of rat brain 125I-labeled MAP2 or 125I-labeled tau factors to 60 peptides derived from(More)
The structure and sequence of rat alpha-tubulin cDNA clone is being described. The 3'-end of the coding region contains the codon for a C-terminal tyrosine, which was previously considered to be post-translationally added to the completed polypeptide chain. A close homology in the coding sequence is observed when a-tubulin from rat and chick are compared,(More)
The nucleotide sequence of a complete rat brain beta-tubulin T beta 15 has been determined from three overlapping cDNA clones. The overall length of the T beta 15 sequence is 1589 bp and shows between 84.5% and 88.6% homology within the coding region as compared with chick and human beta-tubulin sequences. On the other hand, the 3'-non-coding region is(More)
Successive stages in the development of the brine shrimp cyst were used as a model for studying differentiation at the level of mRNA transcription and translation. The poly (A)-containing mRNA from dormant cysts and free-swimming larvae (nauplii) was found to be efficiently translated in a wheat-germ cell-free system, and electrophoretic patterns of(More)
Addition of dimethylsulfoxide at concentrations of 1% and 2% (vol/vol) to cells of mouse neuroblastoma clone NIE-115 in the confluent phase of growth resulted in the production of morphologically differentiated cultures with extensive process formation. Cell maintained in 2% dimethylsulfoxide remained in a stable nondividing condition for periods of up to 4(More)
During screening of a rat spinal cord lambda gt11 cDNA library with poly- and monoclonal antibodies against the postsynaptic glycine receptor a cDNA was isolated which covers an open reading frame encoding a protein of calculated mol. wt 94 kd. Sequence analysis identified a novel type of neuron-specific protein (named neuraxin) which is characterized by an(More)
