High impact information on Col18a1

  • Mouse Col18a1 is expressed in a tissue-specific manner as three alternative variants and is localized in basement membrane zones [1].
  • We show here that in a specific C57BL background, 20% of the Col18a1(-/-) mice developed hydrocephalus, and dilation of the brain ventricles was observed by MRI in all of the mutant mice [2].
  • CONCLUSIONS: The abnormalities in the iris and ciliary body of Col18a1(-/-) mice demonstrate an important role of collagen XVIII for the function of ocular BMs [3].
  • The mouse gene for the alpha 1 chain of type XVIII collagen (Col18a1) is more than 102 kb and consists of 43 exons [4].
  • In addition, using an interspecific backcross panel, we have shown that the murine Col18a1 locus is on chromosome 10, close to the loci for Col6a1 and Col6a2 [5].

Anatomical context of Col18a1

 

Other interactions of Col18a1

  • With fiber-FISH, Col18a1, Col6a1, and Col6a2 were shown to be in a head-to-tail configuration with respective intergenic distances of about 350 kb and 90 kb [9].
  • We also used MSCs to determine the transcriptional orientations, telomere--5'-->3'--centromere, of both Col13a1 and Col18a1 [9].
  • METHODS AND RESULTS: To test our hypothesis, we bred collagen XVIII-knockout (Col18a1(-/-)) mice into the atherosclerosis-prone apolipoprotein E-deficient (ApoE(-/-)) strain [7].
