Protein : PKA

Connectivity 23
Notes cAMP is a signaling molecule important for a variety of cellular functions. cAMP exerts its effects by activating the cAMP-dependent protein kinase (AMPK), which transduces the signal through phosphorylation of different target proteins. The inactive holoenzyme of AMPK is a tetramer composed of two regulatory and two catalytic subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits. Four different regulatory subunits and three catalytic subunits of AMPK have been identified in humans. The protein encoded by this gene is a member of the Ser/Thr protein kinase family and is a catalytic subunit of AMPK. Alternatively spliced transcript variants encoding distinct isoforms have been observed.

State cAMP-dependent protein kinase catalytic subunit alpha isoform 1
cAMP-dependent protein kinase catalytic subunit alpha isoform 2

State Description Transcript Variant: This variant (1) encodes the longer isoform (1).
Transcript Variant: This variant (2), also known as variant Cs, uses an alternative exon at the 5' end compared to variant 1, which includes a part of the coding region. The resulting isoform (2) has a distinct and shorter N-terminus, as compared to is...
