TRITOPODIN
Tritopodin is the third member and less researched of the podin family proteins and is codified by the gene SYNPO2L. Tritopodin also known under the names synaptopodin 2-like, Myopodin-like and CHAP (cytoskeletal heart-enriched actin-associated protein), is found in heart (Claeys et al. 2009) [1] and skeletal muscle tissue (Beqqali et al. 2010) [2]. Tritopodin share with Myopodin 33% of homology in the Aminoacid sequence, which makes believe similar functions for both proteins. Tritopodin gene it is form by 5 exons and 2 isoforms are postulated: mCHAPa from exon 1,2,3 and 5, as well as mCHAPb that result from a start-codon in exon 4 and the two derives proteins are of 140kDa (mCHAPa) und 110kDa (mCHAPb).
Function
mCHAP is expressed in vivo and in vitro in differentiated skeletal- and heart muscle cells (Beqqali et al. 2010).
Tritopodin interactions
Tritopodin as Synaptopodin and Myopodin localizes in the sarcomeric Z-disc, where they interact with α-actinin and Filamin C, verify by CoIPs and yeast two-hybrid assays [3] [4]
