Leucine 158-161 glycoprotein Ib platelet subunit alpha Homo sapiens 114-123 17083647-0 2007 Trp207Gly in platelet glycoprotein Ibalpha is a novel mutation that disrupts the connection between the leucine-rich repeat domain and the disulfide loop structure and causes Bernard-Soulier syndrome. Leucine 104-111 glycoprotein Ib platelet subunit alpha Homo sapiens 22-42 17083647-6 2007 The crystal structure of the N-terminus of GPIbalpha (PDB: 1SQ0) indicates that Trp207 is completely buried and located in a disulfide loop structure that interacts with the leucine-rich repeat (LRR) domain. Leucine 174-181 glycoprotein Ib platelet subunit alpha Homo sapiens 43-52 10727232-7 2000 These results suggest a vital role for the conserved asparagine residues in the leucine-rich repeats of GP Ib alpha for the structure and functions of this polypeptide. Leucine 80-87 glycoprotein Ib platelet subunit alpha Homo sapiens 104-115 12038791-0 2002 A novel polymorphism, 70Leu/Phe, disrupts a consensus Leu residue within the leucine-rich repeat sequence of platelet glycoprotein Ibalpha. Leucine 24-27 glycoprotein Ib platelet subunit alpha Homo sapiens 118-138 12038791-3 2002 Here we report a new polymorphism, Leu/Phe at residue 70 of GPIbalpha, which disrupts the consensus sequence of the LRR in the vWF binding domain. Leucine 35-38 glycoprotein Ib platelet subunit alpha Homo sapiens 60-69 10996832-6 2000 This mutation, CTC:wild-type to CCC:mutant, is similar to that of another African American family where the resulting leucine to proline substitution in the 5(th) leucine-rich repeat of GP Ib alpha is responsible for the observed BSs phenotype. Leucine 118-125 glycoprotein Ib platelet subunit alpha Homo sapiens 186-197 12693941-7 2003 This substitution modified a conserved residue in the COOH-terminal region flanking the single-copy leucine-rich domain of GPIbbeta. Leucine 100-107 glycoprotein Ib platelet subunit alpha Homo sapiens 123-131 11948601-9 2002 Replacement of the N-terminal flanking sequence and the first leucine-rich repeat resulted in lower GP Ibalpha/vWf bond strengths than the wild-type human GP Ibalpha/vWf bond strength (P < 0.05). Leucine 62-69 glycoprotein Ib platelet subunit alpha Homo sapiens 100-110 10713059-7 2000 GPIbalpha-CaM bound with similar affinity to recombinant VWF A1, to multimeric plasma VWF, and to a fragment of dispase-digested plasma VWF (residues Leu(480)/Val(481)-Gly(718)). Leucine 150-153 glycoprotein Ib platelet subunit alpha Homo sapiens 0-9 8664285-16 1996 These findings indicate that the sulfated tyrosine/anionic GP Ibalpha residues Tyr-276-Glu-282 are important for the binding of thrombin and botrocetin-dependent binding of thrombin and the botrocetin-dependent binding of vWF, but that vWF also interacts with residues within His-1-Leu-275. Leucine 282-285 glycoprotein Ib platelet subunit alpha Homo sapiens 59-69 10648402-2 2000 The vWf-binding site on GP Ib-IX-V is within the N-terminal 282 residues of GP Ibalpha, which consist of an N-terminal flanking sequence (His-1-Ile-35), 7 leucine-rich repeats (Leu-36-Ala-200), a C-terminal flank (Phe-201-Gly-268), and a sulfated tyrosine sequence (Asp-269-Glu-282). Leucine 155-162 glycoprotein Ib platelet subunit alpha Homo sapiens 76-86 10648402-2 2000 The vWf-binding site on GP Ib-IX-V is within the N-terminal 282 residues of GP Ibalpha, which consist of an N-terminal flanking sequence (His-1-Ile-35), 7 leucine-rich repeats (Leu-36-Ala-200), a C-terminal flank (Phe-201-Gly-268), and a sulfated tyrosine sequence (Asp-269-Glu-282). Leucine 177-180 glycoprotein Ib platelet subunit alpha Homo sapiens 76-86 9639514-6 1998 One, inherited from a maternal allele, a T777 --> C point mutation in GPIbalpha converting Cys65 --> Arg within the second leucine rich repeat, the other, a single nucleotide substitution (G2078 --> A) for the tryptophan codon (TGG) causing a nonsense codon (TGA) at residue 498 within the transmembrane region of GPIbalpha, inherited from a mutant paternal allele.

Leucine 125-132 glycoprotein Ib platelet subunit alpha Homo sapiens 149-159 7873390-9 1995 The absence of the leucine 179 in a patient"s GPIb alpha is believed to cause a conformational change in the protein which would account for the lack of binding of most of the MoAbs tested and would be responsible for the absence of von Willebrand factor binding. Leucine 19-26 glycoprotein Ib platelet subunit alpha Homo sapiens 46-56 7873390-10 1995 These results point to the leucine-rich region of GPIb alpha as being required for the correct exposure of the von Willebrand binding site as well as for the correct assembly and stability of the GPIb/IX/V complex on the platelet surface. Leucine 27-34 glycoprotein Ib platelet subunit alpha Homo sapiens 50-60 8407908-10 1993 Analysis of the extracellular domain revealed the presence of 15 tandem Leu-rich repeats of 24 amino acids with homology to GPIb alpha and identified a cleavage site for thrombin near the COOH terminus with similarity to the A alpha chain of fibrinogen, but no hirudin-like sequence was found.
