Summary: Enables PDZ domain binding activity; scaffold protein binding activity; and transcription coregulator binding activity. Involved in several processes, including cellular response to L-glutamate; cellular response to epidermal growth factor stimulus; and regulation of synapse organization. Located in several cellular components, including dendrite; lamellipodium; and neuron projection branch point. Is active in several cellular components, including postsynaptic cytosol; postsynaptic density, intracellular component; and presynaptic cytosol.

These findings suggest that SH2B1-IRSp53 complexes promote the formation of filopodia, neurite initiation, and neuronal branching.
Title: SH2B1 and IRSp53 proteins promote the formation of dendrites and dendritic branches.
Localization study of IRSp53 in the adult brain, suggesting that it acts mainly at the postsynaptic density, that it may play a role in the insulin signaling system, and that it may play different roles in different synapses

ProSAP/Shank and certain ProSAP/Shank-interacting proteins exhibit distinct subcellular localizations in the different cell types, raising the possibility that the function of ProSAP/Shank proteins is more diverse than has been envisaged to date.
Title: Secretory granules of hypophyseal and pancreatic endocrine cells contain proteins of the neuronal postsynaptic density.
These results suggest that PSD-95 interaction is an important determinant of synaptic IRSp53 localization and that the SH3 domain of IRSp53 links activated Rac1/Cdc42 to downstream effectors for the regulation of spine morphogenesis.

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.
