Summary: Enables actin binding activity. Involved in several processes, including modulation of chemical synaptic transmission; regulation of actin filament bundle assembly; and regulation of postsynaptic cytosolic calcium ion concentration. Located in cell periphery and stress fiber. Is active in Schaffer collateral - CA1 synapse and glutamatergic synapse. Is expressed in several structures, including genitourinary system; respiratory system; sensory organ; skeleton; and tooth. Orthologous to human SYNPO (synaptopodin).

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.

mRNA and Protein(s)

NM_001109975.1 → NP_001103445.1 synaptopodin isoform B

See identical proteins and their annotated locations for NP_001103445.1

Status: VALIDATED

Description

Transcript Variant: This variant (B) uses an alternate splice site in the coding region which results in an early stop codon, compared to variant A. The resulting protein (isoform B) has a shorter, distinct C-terminus when compared to isoform A.
