osteoblast differentiation

The process whereby a relatively unspecialized cell acquires the specialized features of an osteoblast, a mesodermal or neural crest cell that gives rise to bone.

GO:0007265

Ras protein signal transduction

A series of molecular signals within the cell that are mediated by a member of the Ras superfamily of proteins switching to a GTP-bound active state.

GO:0030335

positive regulation of cell migration

Any process that activates or increases the frequency, rate or extent of cell migration.

GO:1901214

regulation of neuron death

Any process that modulates the frequency, rate or extent of neuron death.

IMP

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).

NAS

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.

IEA

CC

GO:0005925

focal adhesion

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

IDA

CC

GO:0016020

membrane

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

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:0003924

GTPase activity

Catalysis of the reaction: GTP + H2O = GDP + phosphate.

TAS

MF

GO:0005525

GTP binding

Interacting selectively and non-covalently with GTP, guanosine triphosphate.
