What's a GeneRIF?

The binding site for proline-rich peptides is pre-organized. The C-terminus 2a is well ordered in the absence of ligand peptide. Pfn2 binds to the neuronal protein palladin.

Smn knockdown in PC12 cells alters the expression pattern of profilin II, resulting in an increase in the neuronal-specific profilin IIa isoform.
Title: Smn depletion alters profilin II expression and leads to upregulation of the RhoA/ROCK pathway and defects in neuronal integrity.
RhoA/ROCK/PIIa-mediated regulation of actin stability, shown to be essential for neuritogenesis, may constitute a central mechanism throughout neuronal differentiation.
Title: RhoA/ROCK regulation of neuritogenesis via profilin IIa-mediated control of actin stability.
Following hypophysectomy, the actin cytoskeleton of the Sertoli cell shifts to a predominantly depolymerized state, perhaps in part because of decreases in profilin II and espin gene products.
Title: An ex vivo analysis of Sertoli cell actin dynamics following gonadotropic hormone withdrawal.

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.
