Partial cDNA and genomic clones of rat stem cell factor (SCF) have been isolated. Using probes based on the rat sequence, partial and full-length cDNA and genomic clones of human SCF have been isolated. Based on the primary structure of the 164 amino acid protein purified from BRL-3A cells, truncated forms of the rat and human proteins have been expressed(More)
Formation of the adenohypophysis in mammalian embryos occurs via an invagination of the oral ectoderm to form Rathke's pouch, which becomes exposed to opposing dorsoventral gradients of signaling proteins governing specification of the different hormone-producing pituitary cell types. One signal promoting pituitary cell proliferation and differentiation to(More)
The complete DNA sequence of grouper iridovirus (GIV) was determined using a whole-genome shotgun approach on virion DNA. The circular form genome was 139,793 bp in length with a 49% G + C content. It contained 120 predicted open reading frames (ORFs) with coding capacities ranging from 62 to 1,268 amino acids. A total of 21% (25 of 120) of GIV ORFs are(More)
The purification and cloning of a novel metalloproteinase inhibitor (MI or TIMP-2) related to tissue inhibitor of metalloproteinases (TIMP) has been recently described by our laboratory (DeClerck, Y.A., Yean, T. D., Ratzkin, B.J., Lu, H.S., and Langley, K.E. (1989) J. Biol. Chem. 264, 17445-17453; Boone, T.C., Johnson, M.J., DeClerck, Y.A., and Langley,(More)
Pit-1 is a pituitary-specific transcription factor, which regulates the expression of growth hormone, prolactin, and thyroid stimulating hormone-beta genes. We previously reported the expression of a Pit-1 gene from ayu (Plecoglossus altivelis), which is an important cultivated food fish in Taiwan and Japan. Comparison of ayu Pit-1 with that of salmon,(More)
Purine nucleoside phosphorylase (PNP) is a key enzyme in the purine salvage pathway. It catalyses the reversible phosphorolysis of purine (2'-deoxy)ribonucleosides to free bases and (2'-deoxy)ribose 1-phosphates. Here, a novel piscine viral PNP gene that was identified from grouper iridovirus (GIV), a causative agent of an epizootic fish disease, is(More)
Purine nucleoside phosphorylase (PNP) catalyzes the reversible phosphorolysis of purine ribonucleosides to the corresponding free bases and ribose 1-phosphate. The crystal structure of grouper iridovirus PNP (givPNP), corresponding to the first PNP gene to be found in a virus, was determined at 2.4 A resolution. The crystals belonged to space group R3, with(More)
Perpendicular Spin-Transfer Torque (STT) MRAM is a promising technology in terms of read/write speed, low power consumption and non-volatility, but there has not been a demonstration of high density manufacturability at small geometries. In this paper we present an unprecedented demonstration of a robust STT-MRAM technology designed in a 2x nm CMOSembedded(More)
