CATEGORY

regulatory

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus
text	during spermatid elongation, it localizes to the nucleus of round spermatids but exits the nucleus to the cytoplasm as cells differentiate to elongated spermatids

basic FUNCTION	coactivator putatively involved in distinct cellular differentiation programm
	activates CREM in a phosphorylation-independent fashion
	required for normal sperm maturation and morphology, is not essential for testicular gene expression

CELLULAR PROCESS	cell life, differentiation

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

CREM–FHL5 complex mediates the expression of many post-meiotic genes that are essential for normal spermatogenesis, thus providing a tissue-specific modulation mechanism for CREM transcription activity

INTERACTION

DNA

RNA

small molecule

protein	activating CREB and CREM independently of CREBBP
	KIF17b (interaction restricted to specific stages of spermatogenesis)
	interact with CREM, a DNA binding transcriptional regulator necessary for spermiogenesis
	interacts with SPAG8, which suggests that SPAG8 could be associated with FHL5 during spermatogenesis
