Chromosome 3 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 3 spans more than 198 million base pairs (the building material of DNA ) and represents about 6.5 percent of the total DNA in cells .
This gene, a member of the histidine triad gene family, encodes a diadenosine P1,P3-bis(5'-adenosyl)-triphosphate adenylohydrolase involved in purine metabolism. The gene encompasses the common fragile site FRA3B on chromosome 3, where carcinogen -induced damage can lead to translocations and aberrant transcripts of this gene.
There is only one known protein isoform in humans, which is 232 amino acids long and has a predicted molecular weight of 26.9 kDa. [3] It has a predicted isoelectric point of 9. [ 4 ] The protein contains a transmembrane domain near the C-terminus .
B- and T-lymphocyte attenuator or BTLA (also known as cluster of differentiation 272 or CD272) is a protein that belongs to the CD28 immunoglobulin superfamily (IgSF) which is encoded by the BTLA gene located on the 3rd human chromosome. [5] [6] BTLA was first discovered in 2003 as an inhibitor of Th1 expansion and it became the 3rd member of ...

In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...
Deoxyribonuclease gamma (also termed DNase γ, deoxyribonuclease 1L3, DNASE1L3, of deoxyribonuclease I like 3) is an enzyme that in humans is encoded by the DNASE1L3 (also termed the deoxyribonuclease 1L3 or deoxyribonuclease 1 like 3) gene. This gene's is located on chromosome 3's "p arm", i.e., short arm, between region 1, band 4, sub-band 3 ...
The words homozygous, heterozygous, and hemizygous are used to describe the genotype of a diploid organism at a single locus on the DNA. Homozygous describes a genotype consisting of two identical alleles at a given locus, heterozygous describes a genotype consisting of two different alleles at a locus, hemizygous describes a genotype consisting of only a single copy of a particular gene in an ...
