Type Comment Proteins
SIGD_ARATH-2 SIGD_ARATH function Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released. Regulates transcription of the ndhF gene which codes for a subunit of the plastid NDH [NAD(P)H dehydrogenase] complex.
SIGD_ARATH-2 SIGD_ARATH similarity Belongs to the sigma-70 factor family.
SIGD_ARATH-2 SIGD_ARATH tissue specificity Mostly expressed in leaves, and to a lesser extent in roots. Present in seedlings.
