FunFam 19090: Proto-oncogene tyrosine-protein kinase LCK

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 3 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Protein tyrosine kinase activity GO:0004713
Catalysis of the reaction: ATP + a protein tyrosine = ADP + protein tyrosine phosphate.
1 P42683 (/ISS)
Protein serine/threonine phosphatase activity GO:0004722
Catalysis of the reaction: protein serine phosphate + H2O = protein serine + phosphate, and protein threonine phosphate + H2O = protein threonine + phosphate.
1 P42683 (/ISS)
SH2 domain binding GO:0042169
Interacting selectively and non-covalently with a SH2 domain (Src homology 2) of a protein, a protein domain of about 100 amino-acid residues and belonging to the alpha + beta domain class.
1 P42683 (/ISS)

There are 6 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Cellular zinc ion homeostasis GO:0006882
Any process involved in the maintenance of an internal steady state of zinc ions at the level of a cell.
1 P42683 (/ISS)
Activation of cysteine-type endopeptidase activity involved in apoptotic process GO:0006919
Any process that initiates the activity of the inactive enzyme cysteine-type endopeptidase in the context of an apoptotic process.
1 P42683 (/ISS)
T cell differentiation GO:0030217
The process in which a precursor cell type acquires characteristics of a more mature T-cell. A T cell is a type of lymphocyte whose definin characteristic is the expression of a T cell receptor complex.
1 P42683 (/ISS)
Response to drug GO:0042493
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
1 P42683 (/ISS)
Positive regulation of T cell activation GO:0050870
Any process that activates or increases the frequency, rate or extent of T cell activation.
1 P42683 (/ISS)
Positive regulation of intrinsic apoptotic signaling pathway GO:2001244
Any process that activates or increases the frequency, rate or extent of intrinsic apoptotic signaling pathway.
1 P42683 (/ISS)

There are 2 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Pericentriolar material GO:0000242
A network of small fibers that surrounds the centrioles in cells; contains the microtubule nucleating activity of the centrosome.
1 P42683 (/ISS)
Membrane raft GO:0045121
Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions.
