Gene: [22q112/GP1BB] glycoprotein Ib (platelet), beta polypeptide;
|
FUN |
[1] The GP1BB gene product participates in blood clotting. It is 1 of the
2 subunits of glycoprotein Ib, which is a major component of the platelet
membrane receptor for von Willebrand factor (GEM:12p13/F8VWF), designated
the GP Ib-IX-V complex, and contributes to the expression of a functional
receptor (Lopez-1988).
[2] The GP1BB glycoprotein can participate in transmembrane signaling through phoshorylation of its intra-cellular domain (Wardell-1989; Yagi-1994)." |
|
GEN |
The gene length: 1.3 kb; exons: 2; introns: 1 (Yagi-1994). |
|
EXP |
The 206-amino acid precursor of GP Ib-beta is synthesized from a 1.0-kb mRNA expressed by megakaryocytes." |
|
MOP |
The alpha subunit of glycoprotein Ib is encoded by GP1BA gene (GEM:17p1/GP1BA)." |
|
MAF |
The PNUTL1 and GP1BB (GEM:22q112/GP1BB) genes are encoded on the same DNA strand, overlapping with the same transcriptional orientation (McKie-1997)." |
