Protocadherin 11 X-linked,also known asPCDH11X,is aproteinwhich in humans is encoded by thePCDH11Xgene.[5][6]

Function

[edit]

This gene belongs to theprotocadheringene family, a subfamily of thecadherinsuperfamily. The encoded protein consists of an extracellular domain containing 7 cadherin repeats, a transmembrane domain and a cytoplasmic tail that differs from those of the classical cadherins. The gene is located in a major X/Y block of homology and its Y homolog (PCDH11Y), despite divergence leading to coding region changes, is the most closely related cadherin family member. The protein is thought to play a fundamental role incell–cell recognitionessential for the segmental development and function of thecentral nervous system.Neuronal self-avoidanceis intricately linked toprotocadherinactivity. It also plays a role in structural cell-to-cell adherence. Transcripts arising from alternative splicing encode isoforms with variable cytoplasmic domains.[5]

Clinical significance

[edit]

In agenome-wide association study,the PCDH11X gene has been linked as a risk factor in late onsetAlzheimer's disease,[7]but other studies on different populations[8][9][10][11]could not confirm the initial association. The clinical significance of this gene is unclear, and the gene might play different roles in different population specific contexts.
