FAMILY

CATEGORY

structural protein

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus
text	in tripartite segments of synaptonemal complexes, between lateral elements in the nucleus

basic FUNCTION	transverse filament protein involved in the structural organization of meiotic prophase chromosomes
	primary determinant of synaptonemal complexes assembly that plays a key role in synapsis of homologous chromosomes
	involved with SYCP1 and SYCE2 in synaptonemal complex assembly
	in addition to their roles as synaptonemal complex components, SYCP1 and SYCP3 act at the centromeres to promote the establishment and/or maintenance of centromere pairing and, by doing so, improve the segregation fidelity of mammalian meiotic chromosomes
	SYCP1 and SYCE3 form a joint bilayered central structure

CELLULAR PROCESS	cell cycle,division,meiosis

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component	constituent of synaptonemal complex protein 1, axial element
	SYCE1 interacts more directly with SYCP1 and could thus anchor the central element proteins to the transverse filaments

INTERACTION

DNA

binding

RNA

small molecule

protein	interact with SYCE1, SYCE2, for their localisation to the central element
	with SCYP2, interact in extracts of meiotic cells
	interaction with FKBP6 (crucial factor in spermatogenesis because of its interplay with the synaptonemal complex protein SYCP1)
	PLK1, phosphorylates central element proteins SYCP1 and TEX12, and PLK-mediated phosphorylation of central element proteins is required for meiotic prophase exit
	disruption of SYCE2 and TEX12 (a fourth central element protein) localization to the central element abolishes central alignment of the N-terminal region of SYCP1
	PUM1 facilitates the transition of the late meiotic prophase I oocyte from pachytene to diplotene stage by regulating SYCP1 protein
	C1ORF146 interacts with synaptonemal complex protein 1 (SYCP1) and synaptonemal complex central element 3 (SYCE3)
