SYNPO2

Identity

Other names	Myopodin
	synaptopodin 2
Hugo	SYNPO2
Location	4q27

Note	Myopodin probably represents an alternative splicing variant of synaptopodin 2. The predicted synaptopodin 2 contains 1021 amino acid and myopodin 698. The extra 323 amino acid in synaptopodin 2 is located at the N-terminus.

DNA/RNA

	Genome structure of myopodin and synaptopodin 2. Green represents exons of myopodin, and orange synaptopodin 2. Introns are indicated with lines.
Description	The genome sequence of myopodin contains 6.8 Kb, while synaptopodin 2 38 kb.
Transcription	A typical messenger RNA of myopodin is 4.2-4.4 kb, and synaptopodin 2 6.7 kb.
Pseudogene	Unknown

Protein

	Protein structure of myopodin and synaptopodin 2. Orange represents sequence unique to synaptopodin 2, Green myopodin. Black stripe represents sequence homologous to synaptopodin 1.

Description	A nuclear localization signal is identified in N-terminus region of myopodin. Myopodin also contains six stretches of homologous sequences with synaptopodin 1.
Expression	Skeletal muscle, prostate, large and small intestine.
Localisation	Nucleus, cytoplasm.
Function	Actin bundling.
Homology	Synaptopodin

Mutations

Germinal	Not known
Somatic	Deletion

Implicated in

Disease	Prostate cancer and urothelial cell carcinoma.
Prognosis	Deletion preferentially occurs in aggressive type of prostate cancer. Loss of expression in nucleus in urothelial cell carcinoma is predictive of poor clinical outcome.
Cytogenetics	Not known
