Interacting selectively with troponin C, the calcium-binding subunit of the troponin complex.

Catalysis of the reaction: ATP + ribonucleotide (n) + ribonucleotide (m) = AMP + diphosphate + ribonucleotide (n+m).

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

Penetrating at least one phospholipid bilayer of the Golgi complex membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer.

Catalysis of the reaction: (S)-2-hydroxy-acid + O2 = 2-oxo acid + H2O2.

The mitotic divisions of the primary spermatogonial cell (a primordial male germ cell) to form a cyst of secondary spermatogonia (primary spermatocytes).

regulation of DNA replication initiation

Any process that modulates the frequency, rate or extent of initiation of DNA replication; the process by which DNA becomes competent to replicate. In eukaryotes, replication competence is established in early G1 and lost during the ensuing S phase.

The phase of growth and gene expression that male germ cells undergo as they enter the spermatocyte stage. The cells grow in volume and transcribe most of the gene products needed for the morphological events that follow meiosis.

Thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone; usually approximately 0.1 um wide, 5-10 um long, can be up to 50 um long in axon growth cones; contains a loose bundle of about 20 actin filaments oriented with their plus ends pointing outward.

Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + dolichyl phosphate = UMP + N-acetyl-D-glucosaminyl-diphosphodolichol.

The process whose specific outcome is the progression of a male gamete over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

integral to endoplasmic reticulum membrane

Penetrating at least one phospholipid bilayer of an endoplasmic reticulum membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer.
