Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Chromosomal protein that binds to methylated DNA. It can bind specifically to a single methyl-CpG pair. It is not influenced by sequences flanking the methyl-CpGs. Mediates transcriptional repression through interaction with histone deacetylase and the corepressor SIN3A. Binds both 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC)-containing DNA, with a preference for 5-methylcytosine (5mC).SUBUNIT Interacts with FNBP3 (By similarity). Interacts with CDKL5 (PubMed:15917271). Interacts with ATRX; MECP2 recruits ATRX to pericentric heterochromatin in neuronal cells (By similarity). Interacts with NCOR2 (By similarity). Interacts with TBL1XR1; bridges interaction between MECP2 and NCOR1 (PubMed:28348241). Interacts with TBL1X; recruits TBL1X to the heterochromatin foci (PubMed:28348241).INTERACTION Colocalized with methyl-CpG in the genome. Colocalized with TBL1X to the heterochromatin foci.ALTERNATIVE PRODUCTS Present in all adult somatic tissues tested.PTM Phosphorylated on Ser-423 in brain upon synaptic activity, which attenuates its repressor activity and seems to regulate dendritic growth and spine maturation.DISEASE The disease may be caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease may be caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry. The MECP2 gene is mutated in Rett syndrome, a severe neurodevelopmental disorder that almost always occurs in females. Although it was first thought that MECP2 mutations causing Rett syndrome were lethal in males, later reports identified a severe neonatal encephalopathy in surviving male sibs of patients with Rett syndrome. Additional reports have confirmed a severe phenotype in males with Rett syndrome-associated MECP2 mutations.DISEASE The disease is caused by variants affecting the gene represented in this entry. Increased dosage of MECP2 due to gene duplication appears to be responsible for the intellectual disability phenotype.MISCELLANEOUS Ten times higher expression levels than isoform A in brain.SEQUENCE CAUTION Truncated N-terminus.
