title: Rat pineal Gsa, Gia and Goa: relative abundance and development.
abstract: The adult rat pineal gland contains relatively high concentrations of Gsa, low amounts of both Gia and Goa, and undetectable levels of GTa. During development the amounts of 45 kDa Gsa and of Gia remain constant. In contrast, 42 kDa Gsa and Goa are nearly absent at birth and increase in abundance markedly thereafter. GTa is undetectable at any age. It would appear that multiple mechanisms regulate the expression of G-proteins in the pineal gland.
