The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:
"Immunoglobulins
".
FunFam 135810: CD19 antigen, isoform CRA_a
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

| GO Term | Annotations | Evidence |
|---|---|---|
|
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

Signal transducer activity, downstream of receptor GO:0005057
Conveys a signal from an upstream receptor or intracellular signal transducer, converting the signal into a form where it can ultimately trigger a change in the state or activity of a cell.

1 | P15391 (/TAS) |
|
Phosphatidylinositol-4,5-bisphosphate 3-kinase activity GO:0046934
Catalysis of the reaction: 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + ATP = a 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate + ADP + 2 H(+).

Cellular defense response GO:0006968
A defense response that is mediated by cells.
|
1 | P15391 (/TAS) |
|
Cell surface receptor signaling pathway GO:0007166
A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.

1 | P15391 (/TAS) |
|
Regulation of phosphatidylinositol 3-kinase signaling GO:0014066
Any process that modulates the frequency, rate or extent of signal transduction mediated by the phosphatidylinositol 3-kinase cascade.
|
1 | P15391 (/TAS) |
|
Regulation of complement activation GO:0030449
Any process that modulates the frequency, rate or extent of complement activation.
|
1 | P15391 (/TAS) |
|
Phosphatidylinositol-mediated signaling GO:0048015
A series of molecular signals in which a cell uses a phosphatidylinositol-mediated signaling to convert a signal into a response. Phosphatidylinositols include phosphatidylinositol (PtdIns) and its phosphorylated derivatives.
|
1 | P15391 (/TAS) |
|
Regulation of immune response GO:0050776
Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.
|
1 | P15391 (/TAS) |
|
B cell receptor signaling pathway GO:0050853

|
Positive regulation of release of sequestered calcium ion into cytosol GO:0051281
Any process that activates or increases the frequency, rate or extent of the release into the cytosolic compartment of calcium ions sequestered in the endoplasmic reticulum or mitochondria.
