Summary: Enables mitogen-activated protein kinase kinase binding activity and protein domain specific binding activity. Involved in positive regulation of dephosphorylation and positive regulation of transcription by RNA polymerase II. Acts upstream of or within negative regulation of apoptotic signaling pathway. Located in cytoplasm and microtubule. Is expressed in central nervous system and genitourinary system. Human ortholog(s) of this gene implicated in corpus callosum agenesis-intellectual disability-coloboma-micrognathia syndrome. Orthologous to several human genes including IGBP1 (immunoglobulin binding protein 1). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Report the significance and altered activity of the type 2A protein phosphatase-alpha4 complex in healthy and hypertrophied myocardium.
Title: Expression and regulation of type 2A protein phosphatases and alpha4 signalling in cardiac health and hypertrophy.
both the C-terminal Mid1-binding domain and the PP2Ac-binding determinants are required for Alpha4-mediated protection of PP2Ac from polyubiquitination and degradation.
Title: The E3 ubiquitin ligase- and protein phosphatase 2A (PP2A)-binding domains of the Alpha4 protein are both required for Alpha4 to inhibit PP2A degradation.
Alpha4 (Igbp1) plays a required role in regulating the assembly and maintenance of adaptive PP2A phosphatase complexes.
Title: Alpha4 is an essential regulator of PP2A phosphatase activity.
results show that alpha4, a noncatalytic subunit of protein phosphatase 2A, is required to repress apoptosis in murine cells
Title: The PP2A-associated protein alpha4 is an essential inhibitor of apoptosis.
alpha4 expression differentially increased or decreased phosphorylation of endogenous phosphoproteins, consistent with opposing effects on PP2A and PP6
Title: The alpha4 regulatory subunit exerts opposing allosteric effects on protein phosphatases PP6 and PP2A.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
