Protein Structure

UniProt Annotation

Function

Transcriptional coactivator of serum response factor (SRF) with the potential to modulate SRF target genes. Suppresses TNF-induced cell death by inhibiting activation of caspases; its transcriptional activity is indispensable for the antiapoptotic function. It may up-regulate antiapoptotic molecules, which in turn inhibit caspase activation. {ECO:0000269PubMed:19350017}.

Subcellular Localization

Cytoplasm. Nucleus. Note=Binding to globular actin is required to maintain cytoplasmic localization. Nuclear localization is regulated by MICAL2, which mediates depolymerization of nuclear globular actin, promoting retention of MKL1 in the nucleus and subsequent formation of an active complex with SRF (By similarity). {ECO:0000250}.

Disease Associations

Tissue Specificity

Expressed in heart, brain, spleen, lung, liver, muscle, kidney and testis.
