BACKGROUND Large-scale partial sequencing of cDNA libraries to generate expressed sequence tags (ESTs) is an effective means of discovering novel genes and characterizing transcription patterns in different tissues. To catalogue the identities and expression levels of genes in the cardiovascular system, we initiated large-scale sequencing and analysis of(More)
The RING domain is a conserved zinc finger motif, which serves as a protein-protein interaction interface. Searches of a human heart expressed sequence tag data base for genes encoding the RING domain identified a novel cDNA, named striated muscle RING zinc finger protein (SMRZ). The SMRZ cDNA is 1.9 kilobase pairs in length and encodes a polypeptide of 288(More)
BACKGROUND The variability of the phenotypic expression of left ventricular hypertrophy (LVH) in patients with hypertrophic cardiomyopathy (HCM) indicates a potential role for additional modifying genes. Variants of angiotensin-I converting enzyme (ACE) gene have been implicated in cardiac hypertrophy. To assess whether ACE genotypes influence the(More)
Cardiac hypertrophy is an adaptive response to chronic hemodynamic overload. We employed a whole-genome approach using expressed sequence tags (ESTs) to characterize gene transcription and identify new genes overexpressed in cardiac hypertrophy. Analysis of general transcription patterns revealed a proportional increase in transcripts related to(More)
We have isolated and analyzed the structure of the genes coding for the alpha and beta forms of the human cardiac myosin heavy chain (MYHC). Detailed analysis of four overlapping MYHC genomic clones shows that the alpha-MYHC and beta-MYHC genes constitute a total length of 51 kilobases and are tandemly linked. The beta-MYHC-encoding gene, predominantly(More)
Myocardial cells were isolated after treatment with collagenase (0.05%) and hyaluronidase (0.1%) by discontinuous-gradient centrifugation on 3% Ficoll. Nuclei derived from these myocardial cells were then fractionated on a discontinuous sucrose density gradient with the following steps: (I) 2.0M/2.3M, (II) 2.3M/2.4M, (III) 2.4M/2.5M, (IV) 2.5M/2.6M, and (V)(More)
We have isolated and sequenced a human heart cDNA clone encoding a novel LIM-only protein. This full-length cDNA clone has a predicted open reading frame (ORF) encoding 280 amino acids. The ORF of this cDNA codes for a LIM-only protein that possesses four repeats of LIM domain and an extra zinc finger and this putative protein is named four-and-a-half LIM(More)
A full-length cDNA clone encoding a novel LIM-only protein was isolated and sequenced from a human fetal heart cDNA library. This full-length clone consists of 1416 base pairs and has a predicted open reading frame (ORF) encoding 279 amino acids. The ORF of this polypeptide codes for the human heart-specific four and a half LIM-only protein 2 (FHL2). It(More)
A partial cDNA clone, RLC34, was isolated from a rat brain cDNA library. Its sequence exhibits high identity with BAT3 (88.4% and 94.9% for DNA and the deduced amino acid sequence, respectively), a gene located within the region of human major histocompatibility complex III (MCHIII region). RLC34 detected a transcript the same size in human and rat, similar(More)
