CC   -!- FUNCTION: Atypical homeodomain protein which does not bind DNA and
CC       is required to modulate cardiac growth and development. Acts via
CC       its interaction with SRF, thereby modulating the expression of
CC       SRF-dependent cardiac-specific genes and cardiac development.
CC       Prevents SRF-dependent transcription either by inhibiting SRF
CC       binding to DNA or by recruiting histone deacetylase (HDAC)
CC       proteins that prevent transcription by SRF. Overexpression causes
CC       cardiac hypertrophy (By similarity). May act as a tumor
CC       suppressor. Acts as a co-chaperone for HSPA1A and HSPA1B chaperone
CC       proteins and assists in chaperone-mediated protein refolding
CC       (PubMed:27708256). {ECO:0000250|UniProtKB:Q8R1H0,
CC       ECO:0000269|PubMed:27708256}.
CC   -!- SUBUNIT: Interacts with serum response factor (SRF). Component of
CC       a large complex containing histone deacetylases such as HDAC2 (By
CC       similarity). Interacts with the acetylated forms of HSPA1A and
CC       HSPA1B. Interacts with HSPA8 (PubMed:27708256).

CC       of cancer such as lung cancer, choriocarcinoma, head and neck
