The retention in the endoplasmic reticulum (ER) lumen of soluble resident proteins. Sorting receptors retrieve proteins with ER localization signals, such as KDEL and HDEL sequences or some transmembrane domains, that have escaped to the cis-Golgi network and return them to the ER. Abnormally folded proteins and unassembled subunits are also selectively retained in the ER.

The process by which the anatomical structures of the epidermis are generated and organized. Morphogenesis pertains to the creation of form. The epidermis is the outer epithelial layer of a plant or animal, it may be a single layer that produces an extracellular material (e.g. the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species.

The process of directing proteins towards the lysosome using signals contained within the protein.

The process whose specific outcome is the progression of an organismal system over time, from its formation to the mature structure. A system is a regularly interacting or interdependent group of organs or tissues that work together to carry out a given biological process.

The process of directing proteins towards the vacuole using signals contained within the protein.

The process whose specific outcome is the progression of a gland over time, from its formation to the mature structure. A gland is an organ specialised for secretion.

vacuolar protein processing or maturation

The process whose specific outcome is the progression of the sebaceous gland over time, from its formation to the mature structure.

The process of directing proteins towards the peroxisome using signals contained within the protein.

The process of directing proteins towards and into the mitochondrion, mediated by mitochondrial proteins that recognize signals contained within the imported protein.

The cleavage of proteins, usually near the N terminus, during the process of import into the mitochondrion; several different peptidases mediate cleavage of proteins destined for different mitochondrial compartments.
