In the past, centrosome maturation has been described as the change in microtubule nucleation potential that occurs as cells pass through specific phases of the cell cycle. It is suggested that the idea of centrosome maturation be expanded to include gain of functions that are not necessarily related to microtubule nucleation. Some of these functions could(More)
We have described methods for the preparation of lysates and isolation of centrosomes from parthenogenetically activated oocytes of the surf clam, S. solidissima. Although oocyte availability is seasonal, between June and August as much as 2 liters of lysate can be generated by a single person. Since lysate can be stored frozen at -80 degrees C with no(More)
We generated nucleotide sequences for H-2Kk and H-2Dk from the C3H mouse, as well as for a genomic clone of H-2Db, in order to conduct an evolutionary analysis of the H-2 genes from three haplotypes, k, d, and b. H-2Kk from both the C3H and AKR strains, H-2Kd, H-2Kb, H-2Dk, H-2Ld, H-2Dd, H-2Db, and H-2Dp DNA sequences were aligned, and the alignments used(More)
H-2L-null variants were immunoselected from a transfected murine fibroblast cell line carrying a single copy H-2L gene, and were characterized to determine the basis for the loss of this MHC class I cell surface product. Molecular analysis indicated that inactivation of H-2L expression in nearly every null clone resulted from an apparent deletion or(More)
Centrosome-dependent microtubule nucleation involves the interaction of tubulin subunits with pericentriolar material. To study the biochemical and structural basis of centrosome-dependent microtubule nucleation, centrosomes capable of organizing microtubules into astral arrays were isolated from parthenogenetically activated Spisula solidissima oocytes.(More)
The UV-induced, C3H fibrosarcoma, 1591, expresses at least three unique MHC class I antigens not found on normal C3H tissue. Here we report the complete DNA sequence of the three novel class I genes encoding these molecules, and describe in detail the recognition of the individual products by tumor-reactive and allospecific CTL. Remarkably, although C3H(More)
The C3HfB/HeN (C3Hf) mouse strain expresses an H-2Kk molecule, previously denoted H-2Kkv1, that is structurally and functionally distinct from H-2Kk of the parental C3H strain. By molecular genetic analysis, we demonstrate that the C3Hf H-2K gene carries a homozygous coding region mutation relative to the C3H allele, revealing that C3Hf meets the(More)
A large number of H-2K and H-2D cDNA clones from a C3HfB/HeN spleen cDNA library were extensively characterized. All H-2Dk cDNAs were shown to exhibit the short form of exon 8, consistent with the presence of a single lariat branchpoint site within intron 7. Twenty-five H-2Kkm2 cDNAs were found to bear a short exon 8, whereas only two clones were shown to(More)
The adenocarcinoma LT85 was chemically induced in a mouse from a C3Hf colony shown subsequently to be inbred for a gene conversion-like mutation at the H-2K locus, characterized by a clustered four nucleotide substitution in exon 3. The H-2K phenotype of LT85, however, more closely resembles that of C3H rather than the mutant strain now designated C3Hf(More)
