Descriptions

Discoidin domain receptor 1 (DDR1) is a collagen-activated receptor tyrosine kinase with important functions in organogenesis and tissue homeostasis. The autoinhibition of DDR kinase activity is released by a two-step. First, phosphorylation of JM4 (kinase-proximal segment) tyrosines likely ejects JM4 from the cleft between the kinase N- and C-lobes, resulting in low activity similar to that of an inactive kinase alone where the A-loop still blocks the active site. In the second step, phosphorylation of the A-loop frees up the active site, resulting in a fully active kinase. Interestingly, the glycosylation at the Asn211 position could help to maintain the autoinhibitory state during the trafficking of the receptor to the cell surface by imposing steric or electrostatic effects that translate into downstream conformations.

2 GO annotations of cellular component

Name Definition
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
receptor complex Any protein complex that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

4 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
collagen binding Binding to collagen, a group of fibrous proteins of very high tensile strength that form the main component of connective tissue in animals. Collagen is highly enriched in glycine (some regions are 33% glycine) and proline, occurring predominantly as 3-hydroxyproline (about 20%).
metal ion binding Binding to a metal ion.
protein tyrosine kinase collagen receptor activity Combining with collagen and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity by catalysis of the reaction

9 GO annotations of biological process

Name Definition
collagen-activated tyrosine kinase receptor signaling pathway The series of molecular signals initiated by collagen binding to its receptor on the surface of a target cell where the receptor possesses tyrosine kinase activity, and ending with the regulation of a downstream cellular process, e.g. transcription.
female pregnancy The set of physiological processes that allow an embryo or foetus to develop within the body of a female animal. It covers the time from fertilization of a female ovum by a male spermatozoon until birth.
lactation The regulated release of milk from the mammary glands and the period of time that a mother lactates to feed her young.
peptidyl-tyrosine autophosphorylation The phosphorylation by a protein of one or more of its own tyrosine amino acid residues, or a tyrosine residue on an identical protein.
positive regulation of neuron projection development Any process that increases the rate, frequency or extent of neuron projection development. Neuron projection development is the process whose specific outcome is the progression of a neuron projection over time, from its formation to the mature structure. A neuron projection is any process extending from a neural cell, such as axons or dendrites (collectively called neurites).
regulation of extracellular matrix disassembly Any process that modulates the rate, frequency or extent of extracellular matrix disassembly. Extracellular matrix disassembly is a process that results in the breakdown of the extracellular matrix.
smooth muscle cell migration The orderly movement of a smooth muscle cell from one site to another, often during the development of a multicellular organism.
smooth muscle cell-matrix adhesion The binding of a smooth muscle cell to the extracellular matrix via adhesion molecules.
wound healing, spreading of cells The migration of a cell along or through a wound gap that contributes to the reestablishment of a continuous surface.
