ALDEHYDE DEHYDROGENASE 3 FAMILY, MEMBER B2; ALDH3B2


Alternative titles; symbols

ALDEHYDE DEHYDROGENASE 8; ALDH8
ACETALDEHYDE DEHYDROGENASE 8


HGNC Approved Gene Symbol: ALDH3B2

Cytogenetic location: 11q13.2     Genomic coordinates (GRCh38): 11:67,662,155-67,681,252 (from NCBI)


TEXT

Cloning and Expression

Hsu et al. (1995) and Hsu and Chang (1996) reported the cloning, sequencing and expression of the human ALDH8 gene. Hsu and Chang (1996) reported that ALDH8 encodes a deduced 385-amino acid protein with 2 ALDH conserved regions. Northern blot analysis detected expression of ALDH8 in the salivary gland and in no other tissues examined.


Gene Structure

Hsu et al. (1997) determined the structure of the ALDH7 (600466) and ALDH8 genes. The ALDH7 gene spans about 20 kb of genomic DNA and contains 9 coding exons. The ALDH8 gene spans over 10 kb and contains at least 10 exons. The ALDH8 gene contains an in-frame stop codon at the seventeenth codon position from the first initiator methionine. The coding region of the ALDH7 gene shows about 86% nucleotide identity with the corresponding region of the ALDH8 gene. The numbers and positions of the introns of the 2 genes are conserved, suggesting that gene duplication is involved in the expansion of the ALDH gene family. The human ALDH7 and ALDH8 genes have a close evolutionary relationship with human ALDH3 (100660).


Mapping

The International Radiation Hybrid Mapping Consortium mapped the ALDH8 gene to chromosome 11 (U37519).
