Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Plays a role in vesicle-mediated secretory processes. Required for normal accumulation of secretory vesicles in hippocampus, pituitary and pancreatic islets. Required for the accumulation of normal levels of insulin-containing vesicles and preventing their degradation. Plays a role in insulin secretion in response to glucose stimuli. Required for normal accumulation of the neurotransmitters norepinephrine, dopamine and serotonin in the brain. In females, but not in males, required for normal accumulation and secretion of pituitary hormones, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Required to maintain normal levels of renin expression and renin release. Seems to lack intrinsic enzyme activity.By similarity
ICA512-TMF regulates dynamics and exocytosis of insulin secretory granules (SGs); binding of ICA512-TMF to SNTB2/beta-2-syntrophin is proposed to restrain SGs mobility and exocytosis by tethering them to the actin cytoskeleton depending on UTRN; the function is inhibited by cytoplasmic ICA512-CFF dimerizing with ICA512-TMF and displacing SNTB2 (By similarity).By similarity
ICA512-CCF translocated to the nucleus promotes expression of insulin and other granule-related genes; the function implicates binding to and regulating activity of STAT5B probably by preventing its dephosphorylation and potentially by inducing its sumoylation by recruiting PIAS4 (By similarity). Enhances pancreatic beta-cell proliferation by converging with signaling by STAT5B and STAT3 (PubMed:18178618). ICA512-CCF located in the cytoplasm regulates dynamics and exocytosis of insulin secretory granules (SGs) by dimerizing with ICA512-TMF and displacing SNTB2 thus enhancing SGs mobility and exocytosis (By similarity).By similarity1 Publication

Homodimer; shown for the unprocessed protein (proICA512) in the endoplasmic reticulum and resolved during protein maturation as ICA512-TMF seems to be predominantly monomeric in secretory granules; however, ICA512-CCF interacts with ICA512-TMF disrupting the ICA512-TMF:SNTB2 complex. The isolated lumenal RESP18 homology domain has been shown to form disulfide-linked homooligomers.

Interacts (via cytoplasmic domain) with phosphorylated SNTB2; this protects PTPRN against cleavage by CAPN1 to produce ICA512-CCF. Dephosphorylation of SNTB2 upon insulin stimulation disrupts the interaction and results in PTPRN cleavage.

Interacts with SNX19. ICA512-CCF interacts with PIAS4; in the nucleus.

Interacts with STAT5B (phosphorylated); down-regulated by ICA512-CCF sumoylation; ICA512-CCF prevents STAT5B dephosphorylation; ICA512-CCF mediates interaction of STAT5B with PIAS4.

Interacts (via RESP18 homology domain) with insulin and proinsulin.

Interacts with PTPRN2, PTPRA and PTPRE.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iBCD567DAFFFE2A2B
