Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

Plays a role in establishing and maintaining the asymmetric distribution of channels and receptors at the plasma membrane of polarized cells. Forms membrane-associated multiprotein complexes that may regulate delivery and recycling of proteins to the correct membrane domains. The tripartite complex composed of LIN7 (LIN7A, LIN7B or LIN7C), CASK and APBA1 may have the potential to couple synaptic vesicle exocytosis to cell adhesion in brain. Ensures the proper localization of GRIN2B (subunit 2B of the NMDA receptor) to neuronal postsynaptic density and may function in localizing synaptic vesicles at synapses where it is recruited by beta-catenin and cadherin. Required to localize Kir2 channels, GABA transporter (SLC6A12) and EGFR/ERBB1, ERBB2, ERBB3 and ERBB4 to the basolateral membrane of epithelial cells (By similarity).By similarity

Forms two exclusive ternary complexes with CASK and APBA1 or CASKIN1. Can also interact with other modular proteins containing protein-protein interaction domains like MPP5, MPP6, MPP7, DLG1, DLG2 and DLG3 through its L27 domain.

Interacts with DLG4, GRIN2B and MARCH11 as well as CDH1 and CTNNB1, the channels KCNJ12/Kir2.2, KCNJ4/Kir2.3 and probably KCNJ2/Kir2.1 and SLC6A12/BGT-1 via its PDZ domain. The association of LIN7A with cadherin and beta-catenin is calcium-dependent, occurs at synaptic junctions and requires the actin cytoskeleton.

Interacts with EGFR, ERBB2, ERBB3 and ERBB4 with both PDZ and KID domains. Associates with KIF17 via APBA1.

Interacts with HTR4.

Forms a tripartite complex composed of DLG1, MPP7 and LIN7 (LIN7A or LIN7C) (By similarity).

<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:iD8D05EF16A93BE7B
