Protein phosphatase 2 scaffold subunit Abeta.

Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform; PP2A is the major phosphatase for microtubule-associated proteins (MAPs). PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase. Cooperates with SGO2 to protect centromeric cohesin from separase- mediated cleavage in oocytes specifically during meiosis I. Activates RAF1 by dephosphorylating it at 'Ser-259' (By similarity).

Non-specific serine/threonine protein kinase.

Shugoshin 1.

BH4_2 domain-containing protein.

Ryanodine receptor 2; Calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering cardiac muscle contraction. Aberrant channel activation can lead to cardiac arrhythmia. In cardiac myocytes, calcium release is triggered by increased Ca(2+) levels due to activation of the L-type calcium channel CACNA1C. Required for cellular calcium ion homeostasis. Required for embryonic heart development (By similarity). The calcium channel activity is modulated by formation of heterotetramers with RYR3; Belongs to t [...]

Serine/threonine-protein phosphatase.

Serine/threonine-protein phosphatase 2A 55 kDa regulatory subunit B; Belongs to the phosphatase 2A regulatory subunit B family.

Serine/threonine-protein phosphatase 2A activator; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Acts as a regulatory subunit for serine/threonine- protein phosphatase 2A (PP2A) modulating its activity or substrate specificity, probably by inducing a conformational change in the catalytic subunit, a proposed direct target of the PPIase. Can reactivate inactive phosphatase PP2A-phosphatase methylesterase complexes (PP2A(i)) in presence of ATP and Mg(2+). Reversibly stimulates the variable phosphotyr [...]
