In maize, the Rp3 gene confers resistance to common rust caused by Puccinia sorghi. Flanking marker analysis of rust-susceptible rp3 variants suggested that most of them arose via unequal crossing over, indicating that rp3 is a complex locus like rp1. The PIC13 probe identifies a nucleotide binding site-leucine-rich repeat (NBS-LRR) gene family that maps to the complex. Rp3 variants show losses...

Cytoplasmic dynein is a motor protein complex involved in microtubule-based cargo movement. Previous biochemical evidence suggests that dynein light chain subunits also exist outside the dynein complex. Here we show that the dynein light chain rp3 is present in both the cytoplasm and the nucleus. Nuclear rp3 binds to and assembles with the transcription factor SATB1 at nuclear matrix-associated...

A 16-kb DNA fragment designated Rp3-1 and cloned from the genome of rat-derived Pneumocystis carinii was found to contain sequences that were repeated approximately 70 times per genome. The repeated sequences in Rp3-1 spanned at least 10.4 kb. Sequences in Rp3-1 were present on each of the 16 P. carinii chromosomes resolved by field inversion gel electrophoresis. Most of the P. carinii genomic ...

The protein product of the novH oncogene, a member of the CCN family, is structurally related to the insulin-like growth factor (IGF) binding proteins (IGFBPs). We have characterized aspects of structure, function, and distribution of this protein, which, as IGFBP-related protein 3 (IGFBP-rP3), is a proposed member of the IGFBP Superfamily. Affinity cross-linking experiments performed with bacu...

AIM X linked retinitis pigmentosa (XLRP) has two genetic loci known as "RP2" and "RP3". Clinical features reported to differentiate RP2 from RP3 include a higher prevalence of myopia and primary cone dysfunction in RP2, and late onset night blindness and tapetal reflex in RP3. Members from 14 XLRP families were examined in an attempt to verify these differences. METHODS 16 affected males and ...

RP3, the Research Parallel Processing Prototype, was a research vehicle for exploring the hardware and software aspects of highly parallel computation. RP3 was a shared-memory machine that was designed to be scalable to 512 processors; a 64-processor machine was in operation from October 1988 through March 1991. A parallel-programming environment based on the Mach operating system was developed...

Thyroid epithelial cells frequently express one or more members of the rearranged during transfection/papillary thyroid carcinoma (RET/PTC) fusion oncogene family during early stages of cancer, and fusion gene transcripts have been found in inflammatory conditions of the thyroid such as the autoimmune disease, Hashimoto's thyroiditis. Because these oncogenes encode chimeric proteins, novel RET/...

RP3, or Research Parallel Processing Prototype, was the name given to the architecture of a research vehicle for exploring the hardware and software aspects of highly parallel computation. RP3 was a shared-memory machine designed to be scalable to 512 processors; a 64 processor machine was in operation for two and half years starting in October 1988. The operating system for RP3 was a version o...

Cytoplasmic dynein is a multi-subunit protein complex in which each subunit is encoded by a few genes. How these subunit isoforms are assembled and regulated to mediate the diverse functions of cytoplasmic dynein is unknown. We previously have shown that two highly conserved 14 kDa dynein light chains, Tctex-1 and RP3, have different cargo-binding abilities. In this report, coimmunoprecipitatio...

The Drosophila RP3 motor axon establishes a stereotypic arborisation along the adjoining edges of muscles 6 and 7 by the end of embryogenesis. The present study has examined the role of the target muscles in determining this axonal arborisation pattern. Target muscles were surgically ablated prior to the arrival of the RP3 axon. Following further development of the embryo in culture medium, the...
