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 .
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 ...

[4] [3] The human Y chromosome, consisting of 62,460,029 base pairs from a different cell line and found in all males, was sequenced completely in January 2022. [5] The current version of the standard reference genome is called GRCh38.p14 (July 2023). It consists of 22 autosomes plus one copy of the X chromosome and one copy of the Y chromosome.
The total complement of genes in an organism or cell is known as its genome, which may be stored on one or more chromosomes. A chromosome consists of a single, very long DNA helix on which thousands of genes are encoded. [51]: 4.2 The region of the chromosome at which a particular gene is located is called its locus.
SCN5A is a highly conserved gene [5] located on human chromosome 3, where it spans more than 100 kb. The gene consists of 28 exons, of which exon 1 and in part exon 2 form the 5' untranslated region and exon 28 the 3' untranslated region of the RNA.
Human genetics is the study of inheritance as it occurs in human beings.Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
The human GATA2 gene is located on the long (or "q") arm of chromosome 3 at position 21.3 (i.e. the 3q21.3 locus) and consists of 8 exons. [13] Two sites, termed C-ZnF and N-ZnF, of the gene code for two Zinc finger structural motifs of the GATA2 transcription factor. These sites are critical for regulating the ability of the transcription ...
