Descriptions

SHPTP2 is a widely-expressed Src homology 2 (SH2) domain-containing protein tyrosine phosphatase (PTP) that is important for normal cell development. It plays a critical role in a variety of signal transduction pathways, including growth factor-mediated cell proliferation. Regulation of SHPTP2 activity is, in part, achieved by an intramolecular interaction between the PTP domain containing the catalytic site and the SH2 1 domain, which leads to closed protein conformation and autoinhibition. Accordingly, opening of the SH2 1 and PTP domains is required for the protein to become active. The binding of phosphopeptides to the SH2 1 domain is known to induce the opening event.

6 GO annotations of cellular component

Name Definition
alpha-beta T cell receptor complex A T cell receptor complex in which the TCR heterodimer comprises alpha and beta chains, associated with the CD3 complex; recognizes a complex consisting of an antigen-derived peptide bound to a class I or class II MHC protein.
apical dendrite A dendrite that emerges near the apical pole of a neuron. In bipolar neurons, apical dendrites are located on the opposite side of the soma from the axon.
cell-cell junction A cell junction that forms a connection between two or more cells of an organism; excludes direct cytoplasmic intercellular bridges, such as ring canals in insects.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
protein-containing complex A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.

B cell receptor signaling pathway The series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell.
cell differentiation The cellular developmental process in which a relatively unspecialized cell, e.g. embryonic or regenerative cell, acquires specialized structural and/or functional features that characterize a specific cell. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
cellular response to macrophage colony-stimulating factor stimulus Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a macrophage colony-stimulating factor stimulus.

hematopoietic progenitor cell differentiation The process in which precursor cell type acquires the specialized features of a hematopoietic progenitor cell, a class of cell types including myeloid progenitor cells and lymphoid progenitor cells.
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
