PubMed PubMed Product Detail Paralemmin, also called Paralemmin-1 or PALM, is a widely expressed peripheral membrane protein that is involved in cell structure and shape. A hydrophobic protein, Paralemmin is anchored to the cytoplasmic side of the cell membrane via di-palmitoylation and prenylation of its C-terminal cysteine cluster. Functioning at the synapse to regulate neuronal plasticity and plasma membrane dynamics, Paralemmin can bind to the dopamine receptor D3, thereby reducing D3 expression and subsequent adenylate cyclase activity. Overexpression of Paralemmin induces fibroblasts to extend long filopodia and to assume extreme cell shapes, suggesting involvement in the formation and stabilization of the plasma membrane. Two isoforms of Paralemmin exists due to alternative splicing events.
Function:
Involved in plasma membrane dynamics and cell process formation. Isoform 1 and isoform 2 are necessary for axonal and dendritic filopodia induction, for dendritic spine maturation and synapse formation in a palmitoylation-dependent manner.
Subunit:
Interacts with dopamine receptor DRD3.
Subcellular Location:
Cell membrane; Lipid-anchor; Cytoplasmic side. Cell projection, filopodium membrane; Lipid-anchor. Cell projection, axon (By similarity). Cell projection, dendrite (By similarity). Cell projection, dendritic spine (By similarity). Basolateral cell membrane; Lipid-anchor (By similarity). Apicolateral cell membrane; Lipid-anchor (By similarity). Note=Translocation to the plasma membrane is enhanced upon stimulation of neuronal activity.
Tissue Specificity:
Widely expressed with highest expression in brain and testis and intermediate expression in heart and adrenal gland.
Similarity:
Belongs to the paralemmin family.
