Molecular cloning and characterization of the bovine and human tuftelin genes.

The bovine tuftelin gene was cloned and its structure determined by DNA sequence analysis and comparison to bovine tuftelin cDNA. The analyses demonstrated that the cDNA contains a 1014 bp open reading frame encoding a protein of 338 residues with a calculated molecular weight of 38,630 kDa and an isoelectric point of 5.85.

Conserved gene structure and genomic linkage for D-dopachrome tautomerase (DDT) and MIF.

Macrophage migration inhibitory factor (MIF) and D-dopachrome tautomerase (DDT) are small proteins, which are related both by sequence and by in vitro enzyme activity. Here we show that the gene for DDT in human and mouse is identical in exon structure to MIF. Both genes have two introns that are located at equivalent positions, relative to a twofold repeat in protein structure.

The DiGeorge syndrome minimal critical region contains a goosecoid-like (GSCL) homeobox gene that is expressed early in human development.

The majority of patients with DiGeorge syndrome (DGS) and velocardiofacial syndrome (VCFS) have deletions of chromosomal region 22q11.2. The abnormalities observed in these patients include conotruncal cardiac defects, thymic hypoplasia or aplasia, hypocalcemia, and characteristic facial features.
