## Abstract Oocytes are recognized as a source of regulatory molecules that influence follicular development through an array of actions on granulosa cells. Recently, more and more hormones and signaling molecules were identified during follicular developmental processes; however, the details about

β¦ Synopsis
The leucocyte specific transcript -1 (LST1) represents the human homolog of the mouse B144 transcript, encoded within the tumor necrosis factor (TNF) region of the human major histocompatibility complex class III interval. The gene is localized about 4 kilobases upstream of the lymphotoxin [3 gene. It spans a polymorphic genomic region encompassing the microsatellites TNFd and TNFe in intron 3 and a polymorphic Pvu II restriction site 260 base pairs downstream of the polyadenylation signal. Isolation of a full-length cDNA clone revealed that LST1 codes for IFN-7-inducible 800 nt transcripts, which are present in lymphoid tissues, T cells, macrophages, and histiocyte cell lines. The cDNA contains three long open reading frames (ORF) with the most likely ORF encoding a transmembrane protein. Its close linkage to the TNF genes and pattern of expression point toward a possible role for LST1 in the immune response.

## Summary Copper is an essential element necessary for normal function of numerous enzymes in all living organisms. Uptake of copper into the cell is thought to occur through the membrane protein, SLC31A1 (CTR1), which has been described in a variety of species including yeast, human and mouse. In
Genomic and cDNA clones have been isolated for a new gene (PO22) expressed in mature pollen of alfalfa. PO22 represents a single-or low-copy gene containing 4 introns, 2 transcriptional start sites, and 6oding for a predicted protein of 340 amino acids with no signal peptide and a coiled coil struct
