Velvet complex

Velvet complex is a group of proteins found in fungi and especially molds that are important in reproduction and production of secondary metabolites including penicillin.  The core members of the complex include VeA, LaeA (loss of aflR-expression A), and VelB.  Other proteins including VelC and VosA sometimes function in the complex.  The proteins were first characterized in Aspergillus nidulans.

Some proteins in the complex are light-sensitive, including the founding member, VeA (Velvet A), which was first described in 1965.

Four of these proteins, VeA, VelB, VelC, and VosA, have an approximately 200 amino acid domain called the velvet domain.
