This domain is found in F-box and other domain-containing plant proteins. Its precise function is unknown, but it is thought to be associated with nuclear processes [ (PUBMED:11779830) ]. In fact, several family members are annotated as being similar to transcription factors.
Family alignment:
There are 7450 FBD domains in 7355 proteins in SMART's nrdb database.

Display abstract
A systematic computational analysis of protein sequences containing known nuclear domains led to the identification of 28 novel domain families. This represents a 26% increase in the starting set of 107 known nuclear domain families used for the analysis. Most of the novel domains are present in all major eukaryotic lineages, but 3 are species specific. For about 500 of the 1200 proteins that contain these new domains, nuclear localization could be inferred, and for 700, additional features could be predicted. For example, we identified a new domain, likely to have a role downstream of the unfolded protein response; a nematode-specific signalling domain; and a widespread domain, likely to be a noncatalytic homolog of ubiquitin-conjugating enzymes.
