Gene Information

human ... BAIAP2(10458)

General description

The gene BAIAP2 (BAI1 associated protein 2) is mapped to human chromosome 17q25. The protein has an I-BAR (inverted Bin/amphiphysin/Rvs) domain, a partial Cdc42 (cell division cycle 42)/Rac (v-akt murine thymoma viral oncogene homolog 1) binding domain, Src homology-3 (SH3) domain and a PDZ (PSD95, Dlg1 and zo-1) domain.

Biochem/physiol Actions

BAIAP2 (BAI1 associated protein 2) interaction with CDC42 (cell division cycle 42) is needed for filopodia formation. It is also involved in neuronal growth cone guidance. Mutations in BAIAP2 are associated with attention-deficit hyperactivity disorder and autism. BAIAP2 also participates in emotional modulation of memory strength. It also regulates cell motility and mediates the coupling of actin- associated remodeling with Rho guanosine triphosphatase (GTPase) and kinase signaling pathways.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST75831.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Attention-deficit/hyperactivity disorder (ADHD) is a common chronic neurodevelopmental disorder with a high heritability. Much evidence of hemisphere asymmetry has been found for ADHD probands from behavioral level, electrophysiological level and brain morphology. One previous research has reported possible association between...

Memory performance is the result of many distinct mental processes, such as memory encoding, forgetting, and modulation of memory strength by emotional arousal. These processes, which are subserved by partly distinct molecular profiles, are not always amenable to direct observation....

Filopodia are dynamic actin-based structures that play roles in processes such as cell migration, wound healing, and axonal guidance. Cdc42 induces filopodial formation through IRSp53, an Inverse-Bin-Amphiphysins-Rvs (I-BAR) domain protein. Previous work from a number of laboratories has shown that...

IRSp53 (also known as BAIAP2) is an abundant excitatory postsynaptic scaffolding protein implicated in autism spectrum disorders (ASD), schizophrenia, and attention-deficit/hyperactivity disorder (ADHD). IRSp53 is expressed in different cell types across different brain regions, although it remains unclear how IRSp53...

It is unclear whether the establishment of apical-basal cell polarity during the generation of epithelial lumens requires molecules acting at the plasma membrane/actin interface. Here, we show that the I-BAR-containing IRSp53 protein controls lumen formation and the positioning of the...
