Involvement in diseasei

Non-arteritic anterior ischemic optic neuropathy (NAION)1 Publication
Disease susceptibility is associated with variations affecting the gene represented in this entry.
Disease descriptionAn ocular disease due to ischemic injury to the optic nerve. It usually affects the optic disk and leads to visual loss and optic disk swelling of a pallid nature. Visual loss is usually sudden, or over a few days at most and is usually permanent, with some recovery possibly occurring within the first weeks or months. Patients with small disks having smaller or non-existent cups have an anatomical predisposition for non-arteritic anterior ischemic optic neuropathy. As an ischemic episode evolves, the swelling compromises circulation, with a spiral of ischemia resulting in further neuronal damage.

Mild bleeding tendencies manifest as epistaxis, gingival bleeding, menorrhagia, easy bruising, or prolonged bleeding after dental surgery.

Polymorphismi

Position 161 is associated with platelet-specific alloantigen Siba (PubMed:1586750). Siba- has Thr-161 and Siba+ has Met-161 (PubMed:1586750). Siba is involved in neonatal alloimmune thrombocytopenia (NATP) (PubMed:1586750, PubMed:7632942).2 Publications
Polymorphisms arise from a variable number of tandem 13-amino acid repeats of S-E-P-A-P-S-P-T-T-P-E-P-T in the mucin-like macroglycopeptide (Pro/Thr-rich) domain (PubMed:1577776, PubMed:7632942). Allele D contains one repeat starting at position 415, allele C contains two repeats, allele B (shown here) contains three repeats and allele A contains four repeats (PubMed:1577776). Allele B is associated with susceptibility to nonarteritic anterior ischemic optic neuropathy (PubMed:1577776).2 Publications

Miscellaneousi

Miscellaneous

Platelet activation apparently involves disruption of the macromolecular complex of GP-Ib with the platelet glycoprotein IX (GP-IX) and dissociation of GP-Ib from the actin-binding protein.
Binding sites for vWF and thrombin (the latter site with unknown function) are in the N-terminal part of the molecule.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
