Species TM AA Chromosomal Location Gene Symbol Gene Name Reference
Human - 417 5q23.1 LOX lysyl oxidase
Mouse - 411 18 28.22 cM Lox lysyl oxidase
Rat - 411 18q11 Lox lysyl oxidase
Gene and Protein Information Comments
Alternative splicing of the human gene results in multiple transcript variants, the longest of which encodes the preproprotein that is post-translationally processed to generate a regulatory propeptide and the mature enzyme.

Gene Expression and Pathophysiology Comments
Mutations in the LOX gene are associated with a predisposition to thoracic aortic aneurysms and dissections [1]. Experimental evidence shows that mutant LOX proteins do not transit to the Golgi, do not have copper incorporated, and hence the proteins do not become catalytically active [2]. So, the LOX loss-of-function is due to a secretion defect rather than to a gross protein structural deformity.
