CC -!- FUNCTION: Regulates the dendritic spine distribution of CTTN/cortactin
CC in hippocampal neurons, and thus controls dendritic spinogenesis and
CC dendritic spine maintenance. {ECO:0000269|PubMed:22262902}.
CC -!- SUBUNIT: Interacts with CTTN/cortactin SH3 domain. Interacts with STRN,
CC STRN4/zinedin and MOB4/phocein; this interaction may regulate dendritic
CC spine distribution of STRN and STRN4 in hippocampal neurons. Activation
CC of glutamate receptors weakens the interaction with STRN and STRN4.
CC {ECO:0000269|PubMed:22262902, ECO:0000269|PubMed:23015759}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cell cortex {ECO:0000250}. Cell
CC projection, dendritic spine {ECO:0000269|PubMed:22262902}. Note=Remains
CC associated with dendritic spines even after glutamate stimulation.
