Talk:Nuclear pore
From Wikipedia, the free encyclopedia
Accroding to image from article there is nuclear basket (?= nucleoplasmic basket) and distal ring. --Snek01 09:07, 21 April 2006 (UTC)
[edit] Size of the pore
There are uncited numbers that specify the size of the NPC:
- The entire pore complex has a diameter of about 120 nm, the diameter of the opening is about 50 nm wide and its "depth" is about 200 nm.
I am sure these numbers vary greatly by organizm, but I found a paper on the frog oocytes sizes:
- Hinshaw JE, Carragher BO, Milligan RA. "Architecture and design of the nuclear pore complex." Cell. 1992 Jun 26;69(7):1133-41. PMID 1617726
where they state:
- "Stain penetration between the center and outer regions in each spoke, at a radius of ~465 A, correlates closely with the known radial position of the membrane (r = ~450 A) (Unwin and Milligan, 1982)." [10 A = 1 nm]
and also:
- "The rings have weak 8-fold symmetry and consist of a ~150 A-wide circle of mass centered at a radius of about ~450 A." [10 A = 1 nm]
so these numbers are very different than the ones in the wiki article.

Oops, these number correlate pretty well. I forgot to do the radius to diameter conversion.
