Functions in cell-cell adhesion, cell migration and axon guidance, exerting an attractive or repulsive role depending on its interaction partners (By similarity). Modulates cadherin-dependent cell-cell adhesion and cell sorting (PubMed:20027292, PubMed:19492039). Plays a role in the spatial organization of brain neurons. Plays a role in vascular development. Plays a role in cell-cell adhesion via its interaction with latrophilins that are expressed at the surface of adjacent cells. Mediates axon attraction towards cells expressing ntn1. Mediates axon growth cone collapse and plays a repulsive role in neuron guidance via its interaction with unc-5 family members. Plays a role in the regulation of the density of glutamaergic synapses (By similarity). Plays a role in signaling cascades downstream of fgfr1, and possibly also other fgfr family members (PubMed:14688794). Plays a role in embryonic morphogenesis, but not in embryonic patterning (PubMed:19492039).By similarity3 Publications

<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.
