coated pit

coat·ed pit

specialized depressions on the cell surface involved in receptor-mediated endocytosis; the visible proteinaceous layer on the cytosolic side of the depression provides the coated appearance.

A specialized depression on the cytoplasmic face of the cell membrane, lined by a ‘scaffolding’ protein, clathrin. Coated pits are the 1st stage in forming a coated vesicle, which internalises and degrades receptors for VIP, insulin and other hormones. Coated pits are involved in hormone receptor-mediated endocytosis, and are pivotal in down-regulating hormone activity
