Summary
PHLDB2 (pleckstrin homology like domain family B member 2, HGNC:29573) is a protein-coding gene on chromosome 3q13.2, encoding Pleckstrin homology-like domain family B member 2 (Q86SQ0). Seems to be involved in the assembly of the postsynaptic apparatus.
Enables cadherin binding activity. Involved in several processes, including negative regulation of focal adhesion assembly; regulation of cytoskeleton organization; and regulation of embryonic development. Located in several cellular components, including basal cortex; cytoskeleton; and focal adhesion.

Function. Seems to be involved in the assembly of the postsynaptic apparatus. May play a role in acetyl-choline receptor (AChR) aggregation in the postsynaptic membrane.
Subunit / interactions. Interacts with FLNC. Interacts with AMOTL2; interaction may facilitate PHLDB2 localization to the myotube podosome cortex that surrounds the core. Part of a cortical microtubule stabilization complex (CMSC) composed of KANK1, PPFIA1, PPFIBP1, ERC1/ELKS, PHLDB2/LL5beta, CLASPs, KIF21A and possibly additional interactors; within CMSCs KANK1 and PHLDB2/LL5beta appear to be the core components for targeting of microtubule-binding proteins KIF21A and CLASPs, whereas PPFIA1, PPFIBP1 and ERC1/ELKS serve as scaffolds for protein clustering.
Subcellular location. Cytoplasm. Cell cortex. Membrane. Cell projection. Podosome.
Domain organisation. The PH domain mediates the binding to phosphoinositides.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 167 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
