angiotensin maturation

The process leading to the attainment of the full functional capacity of angiotensin by conversion of renin substrate into mature angiotensin in the blood.

GO:0006508

proteolysis

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

TAS

BP

GO:0006888

ER to Golgi vesicle-mediated transport

The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi.

GO:0048208

COPII vesicle coating

The addition of COPII proteins and adaptor proteins to ER membranes during the formation of transport vesicles, forming a vesicle coat.

GO:0051603

proteolysis involved in cellular protein catabolic process

The hydrolysis of a peptide bond or bonds within a protein as part of the chemical reactions and pathways resulting in the breakdown of a protein by individual cells.

IBA

BP

GO:0060441

epithelial tube branching involved in lung morphogenesis

The process in which a highly ordered sequence of patterning events generates the branched epithelial tubes of the lung, consisting of reiterated combinations of bud outgrowth, elongation, and dichotomous subdivision of terminal units.

Golgi membrane

The lipid bilayer surrounding any of the compartments of the Golgi apparatus.

extracellular space

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

IDA

CC

GO:0005764

lysosome

A small lytic vacuole that has cell cycle-independent morphology and is found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions.

IBA

CC

GO:0005783

endoplasmic reticulum

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

IDA

CC

GO:0005788

endoplasmic reticulum lumen

The volume enclosed by the membranes of the endoplasmic reticulum.

TAS

CC

GO:0005886

plasma membrane

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

TAS

CC

GO:0030134

ER to Golgi transport vesicle

A vesicle that mediates transport from the endoplasmic reticulum to the Golgi complex; bears a coat formed of the COPII coat complex proteins; such vesicles found associated with endoplasmic reticulum (ER) membranes at steady state, and are involved in ER to Golgi (anterograde) vesicle transport.

TAS

CC

GO:0033116

endoplasmic reticulum-Golgi intermediate compartment membrane

The lipid bilayer surrounding any of the compartments of the endoplasmic reticulum (ER)-Golgi intermediate compartment system.

TAS

CC

GO:0043231

intracellular membrane-bounded organelle

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

IDA

CC

GO:0070062

extracellular exosome

A membrane-bounded vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

IDA

MF

GO:0004197

cysteine-type endopeptidase activity

Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile.

IBA

MF

GO:0005515

protein binding

Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
