Actin was the first binding partner of myopodin to be identified. Actin binding was narrowed down to residues 410–563 of murine myopodin <ref> PMID:11673475 </ref>.

Myopodin also binds to α-actinin via its spectrin repeats <ref> PMID:16450054 </ref>. ~~It's believed that synaptopodin family members are~~ involved in the organization and anchoring of actin in ~~the cell~~ and might be ~~necessary~~ for the correct localization of α-actinin. This hypothesis is supported by recent findings where myopodin expression precedes actin and α-actinin expression <ref> PMID:20554076 </ref>.

Myopodin also binds to α-actinin via its spectrin repeats <ref> PMID:16450054 </ref>, <ref> PMID:20554076 </ref> . Myopodin may be generally involved in the organization and anchoring of actin in muscle cells and might be required for the correct localization of α-actinin. This hypothesis is supported by recent findings where myopodin expression precedes actin and α-actinin expression <ref> PMID:20554076 </ref>.

A newly identiﬁed filamin-binding region within the molecule was reported by performing yeast two-hybrid assays using carboxy-terminally and/or amino-terminally truncated constructs <ref> PMID:20554076 </ref>. The interaction was mapped to a fragment encompassing amino acids 240–521 of Myopodin, i.e. a region that contains two of the previously described homology regions shared by myopodin and synaptopodin <ref> PMID:11696420 </ref>. The alternative transcription offers the possibility of expression of two isoforms of Myopodin, which probably differ in their binding properties for these PDZ binding domain detected, however, there is preliminary evidence that the PDZ binding domain from Myopodin interacts with the C terminal part of Synemin <ref> PMID:16631741 </ref>.

Through yeast two-hybrid analysis, was found the interaction between Myopodin and Zyxin both in vitro and in vivo and that this interaction leads to slower migration of prostate cancer cells and reduced invasiveness <ref> PMID:16885336 </ref>.
