Sequence Features

 266Phosphocysteine intermediate.
 329Required for homodimerization.
 25S -> P (in EPM2; atypical form; does not affect glycogen binding). VAR_019465
 28E -> K (in EPM2; does not affect glycogen binding). VAR_019466

 91R -> P (in EPM2; atypical form; learning difficuties with childhood-onset). VAR_019471
 108R -> C (in EPM2; loss of phosphatase activity; reduced self-interaction capacity; disrupts the interaction with PPP1R3C; dbSNP:rs137852915). VAR_019472 dbSNP
 114E -> D. VAR_019473
 140K -> N (in EPM2). VAR_046383
 148N -> Y (in EPM2). VAR_046384
 171R -> H (in EPM2; results in ubiquitin- positive perinuclear aggregates; no effect on glycogen binding; abolishes phosphatase activity; may affect proper folding; dbSNP:rs137852916). VAR_019474 dbSNP
 187T -> A (in EPM2; abolishes interaction with NHLRC1). VAR_019475
 194T -> I (in EPM2; results in ubiquitin- positive perinuclear aggregates; loss of phosphatase activity; affects glycogen binding; reduced self-interaction capacity; abolishes interaction with NHLRC1, PPP1R3C and PRKAA2; no effect on phosphorylation of protein; dbSNP:rs375544596). VAR_019476 dbSNP
 210E -> K (in EPM2). VAR_046385
 240G -> S (in EPM2; impaired phosphatase activity; does not affect glycogen binding; disrupts the interaction with PPP1R3C). VAR_019477
 279G -> S (in EPM2; results in ubiquitin- positive perinuclear aggregates; loss of phosphatase activity; affects glycogen binding; disrupts the interaction with PPP1R3C; dbSNP:rs137852917). VAR_019478 dbSNP
 293Q -> L (in EPM2; results in ubiquitin- positive perinuclear aggregates; may affect proper folding; loss of phosphatase activity; affects glycogen binding; disrupts the interaction with PPP1R3C; dbSNP:rs796052427). VAR_019479 dbSNP
 294Y -> N (in EPM2; results in ubiquitin- positive perinuclear aggregates; impairs phosphatase activity; affects glycogen binding; disrupts the interaction with PPP1R3C). VAR_019480
 301P -> L (in EPM2; impairs protein stability; impairs phosphatase activity; affects glycogen binding; disrupts the interaction with PPP1R3C; dbSNP:rs796052428). VAR_019481 dbSNP
 310L -> W (in EPM2; causes location of isoform 1 at cytoplasmic punctae; does not affect homodimerization of isoform 1 but prevents heterodimerization of isoform 1 and isoform 2). VAR_046386
